Lay not up to yourselves treasures on earth: where the rust, and moth consume, and where thieves break through and steal.

“When He has driven away the disease of vanity, He does well to bring in speech of contempt of riches. For there is no greater cause of desire of money than love of praise; for this men desire troops of slaves, horses accoutred in gold, and tables of silver, not for use or pleasure, but that they may be seen of many; therefore He says, Lay not up for yourselves treasure on earth.”

“(Serm. in Mont. ii. 13.) For if any does a work with the mind of gaining thereby an earthly good, how will his heart be pure while it is thus walking on earth? For any thing that is mingled with an inferior nature is polluted therewith, though that inferior be in its kind pure. Thus gold is alloyed when mixed with pure silver; and in like manner our mind is defiled by lust of earthly things, though earth is in its own kind pure.”

“After he taught us about fasting, he teaches us about almsgiving, and he says, "Do not store up for yourselves treasures on earth." But it seems that this is not true, since it belongs to kings to store up treasure. But it must be said that by "treasures" he understands abundance, and this is twofold, necessary and superfluous: what is not necessary for one person is necessary for another. And therefore, since a king needs many things, he can gather many things. What would be a sin for a simple, private person is not a sin for a king, because the king needs to defend the kingdom. Again, he forbids it to those who seem to place their confidence in riches; hence 1 Timothy, last chapter, 17: "Charge the rich of this world not to be highminded, nor to trust in the uncertainty of their riches"; Baruch 3:16: "Where are the princes of the nations, who fashion (or store up) silver and gold, in which men trust?" Again, he forbids it on account of instability, because riches are quickly lost. And he sets down three things that riches contain: metals, and these are consumed by rust; garments, and these by moths; and certain things which are consumed by neither, such as precious stones. Another reading has "nor by decay." Hence they are destroyed in three ways: either from an intrinsic principle, as the moth which is born in garments — hence, "where rust and moth [consume]"; or from the excess of the possessor, hence "decay"; or sometimes from outsiders, hence he says, "where thieves do not dig through." If someone should say that these things do not happen, it must be said that even if they do not happen, still it often does happen; and if it does not happen, it is nevertheless possible for it to happen — therefore he argues that riches are uncertain. Again, it is explained mystically. Rust appears; the moth is hidden. Hence by rust are meant bodily sins, by the moth, spiritual sins. Again, some sins are those which men commit by themselves, some which are committed with another, and the latter do more harm — hence he says, "nor do thieves dig through," or he says this on account of hidden treasures. Again, by rust the proud are meant; Ecclesiasticus 12:10: "As bronze rusts, so does their wickedness." The moth corrodes garments, and this signifies exterior works, which are corroded by envy; Proverbs 25:20: "As the moth harms the garment, and the worm the wood, so the sadness of a man harms the heart." Again, by thieves is meant vainglory: thieves, that is, demons, who, since they cannot deceive men through other sins, deceive them through vainglory. Again, he sets down the stability of heavenly riches, where he says, "Store up for yourselves treasures in heaven." And here Augustine says: "Store up for yourselves in heaven" — not in some bodily place, but in heaven, that is, in spiritual goods, that is, acquire an abundance of good merits. And he says "for yourselves," not "for God," because nothing accrues to him; Job 35:7: "If you act justly, what will you give him, or what will he receive from your hand?" The Lord also teaches whence this is acquired, namely through almsgiving, saying, Luke 18:22: "Sell all that you have, and give to the poor, and you will have treasure in heaven." For there, that is, in heaven, there will be no corruption, "for this corruptible must put on incorruption," 1 Corinthians 15:53. There follows: "Where your treasure is, there also is your heart." He teaches that the contrary conclusion is harmful, and this because it entails a distraction of the heart: for if you love earthly things, there your heart will be; for where love is, there is the eye — "the eyes of fools are in the ends of the earth." But since there are few who consider this, he therefore shows, by an example, how great the danger is: "The lamp of your body..." And this is first explained concerning the bodily eye; for just as a lamp directs a man's steps, so does the eye. Hence, "if your eye is sound," that is, strong for seeing, "your whole body will be full of light," that is, it will be directed toward right action; "if it is evil," that is, bleary and dim, "your whole body will be full of darkness," that is, all your works will happen in the manner of darkness. "If then the light that is in you is darkness, how great will that darkness itself be?" The light that is in you is the heart and mind. If then it is directed toward the earth, all the senses of man too will be directed toward the earth. Otherwise it is explained concerning the spiritual eye: for light leads to testing, as does man's reason; Proverbs 20:27: "The lamp of the Lord is the breath of man." Hence, if your eye is sound, in such a way that your reason is directed toward God, your whole body, that is, all your members, will be kept from sin; if not, they will be wrapped up in works of darkness. Or "full of light" refers to the resurrection of the saints; below, Matthew 13:43: "Then the just will shine like the sun." Again, by the eye is signified intention: hence whoever wishes to act, intends something; hence if your intention is full of light, that is, directed toward God, your whole body, that is, your operations, will be full of light — and this is understood of things good absolutely. Again, by the eye is understood faith; hence if it is sound, in such a way that it tends toward God, that is, does not waver, and so on; Romans 14:23: "What is not of faith is sin." Again, by the eye is signified the prelate, who is the eye of his subjects; hence when good prelates direct the people, the whole congregation of the people shines with virtues, and so on; Ecclesiasticus 10:2: "As the judge of the people is, so also are his ministers." There follows: "No one can serve two masters," and so on. Because he had said that the storing up of treasure distracts from God, it is therefore said to be something to be shunned, since it not only distracts but alienates from God: "for no one can serve two masters." A slave is one who, as to what he is, belongs to another; but it is impossible for the mind to be borne toward two ends at once and at the same time — I mean ends that are contrary and dissenting. Again, note that some rule so that their subjects may be rightly directed; others, so as to be feared. The Lord and riches are contrary masters; therefore "you cannot serve God and mammon." But note that it is one thing to have riches as a master, another as a slave: for he has them as a master who uses them well and makes fruit from them; but he is a slave of riches who draws no fruit from them; Ecclesiastes 5:12: "There is another evil which I have seen under the sun: riches kept to the hurt of their owner." Now that in which anyone places his end is his god. Hence he who places his end in riches — riches are his god, as is said of those whose "god is the belly," Philippians 3:19. "You cannot serve God and mammon." By mammon can be understood the Devil, who presides over riches, and is as it were his god — not because he is able to give riches, but because he strives to deceive men by means of riches. Hence, just as there is a certain spirit of fornication, so there is a spirit of riches. Augustine explains it otherwise: "no one can [serve two masters]," namely, masters that are contrary; but God and the Devil are contrary. "What agreement has Christ with Belial?" 2 Corinthians 6:15; and in the third Book of Kings 18:21: "How long do you halt between two sides?" And there follows: "or he will bear with the one," that is, the Devil. And he does not say "will love," because the Devil cannot naturally be loved. God is naturally loved; the Devil, however, is only borne with, as Augustine gives the example: if someone desires another's maidservant, he serves that other out of love for the maidservant, not for the master himself; hence he bears with servitude to the master for the sake of the maidservant. So someone bears with servitude to the Devil for the sake of riches. Again, someone could say: I do not place my end in superfluous riches, but in necessary ones. And this the Lord forbids, saying, "Therefore I say to you, be not anxious for your soul," and so on — not because the soul eats, but because it is fitting for man, the soul existing in him. Or, "for your soul," that is, for the life of the soul. And here he destroys the error of the Euchites, who said that apostolic men ought not to labor. But Paul rebukes these, saying, 2 Thessalonians 3:10: "He who does not wish to work, let him not eat." According to the Apostle, therefore, all are bound. But I ask: is it a counsel, or a precept? If a precept, then all are bound; if a counsel, it is clear that not all are bound, since only perfect men are bound to counsels. I say that some things are commanded for their own sake, some for the sake of another: as when someone has taken up the cross in order to go overseas, he is bound to go overseas, but he cannot go unless he seeks a ship — hence seeking a ship is necessary for him. Thus all are bound to preserve life, and therefore they are bound to all the things that serve this end; hence whoever has no means of preserving his life is bound to labor in order to preserve it. What then does he mean by saying, "Be not anxious," and so on? It must be said that anxiety names a foresight joined with eager pursuit; and eager pursuit is a vehement application of the mind. Now in this vehement application there can be sin, namely when one places the mind there as upon an end, and in this way we ought not to be anxious; and therefore it is found in Proverbs 11:7: "The expectation of the anxious will perish." Again, it can happen that the mind intends to acquire superfluous things, and this is forbidden, as is found in Ecclesiastes 2:1: "I said in my heart: I will go, and I will overflow with riches." Again, there can be anxiety because the mind is excessively solicited to acquire temporal and necessary things, and concerning this it is found in 1 Corinthians 2. Again, some are anxious with a certain fear and despair, because they fear that provision will fail them, and this anxiety is forbidden. There follows: "Is not the soul more than food?" He taught us to avoid anxiety even about necessary things, and he sets down arguments. And first this one: he who gave the greater things will give the lesser; but God gave the soul and the body; therefore he who gave these will preserve them. "Behold the birds of the air," and so on — this is another argument: he who provides for the lesser will provide for the greater; but God provides for brute animals; therefore, and so on. First he draws this out with regard to food; second, with regard to clothing. He teaches, then, to avoid anxiety, saying "Behold," that is, consider, "the birds of the air," because wisdom is to be had from them; hence Job 12:7: "Ask the cattle, and they will teach you." Hence, although they have no work by which to acquire bread, nevertheless, and so on. And he mentions three things corresponding to the three things that are required, namely to sow, to reap, and to gather; and as to this he says three things: "they sow not, neither do they reap, nor gather into barns, and yet your heavenly Father feeds them." And he says "your," not "their," because properly he is Father of the rational creature. "He feeds them" — concerning which it is written in Psalm 146:9: "Who gives to the cattle their food," and so on. "Are not you of much more worth than they?" — that is, of greater value? For man is set above all things, as is found in Genesis 1:26: "Let us make man," and so on; and there follows, "that he may have dominion over the fish of the sea, and the birds of the air." And it is not to be understood that apostolic men do not gather provisions; rather it is to be understood that God, in their gathering, delivers the just from tribulation, as he delivered Daniel from the lions' den, and the three boys from the furnace. And I do not say that those existing in tribulation ought not to act so as to be delivered, since the Lord commanded that they should flee from one city into another; but it is to be understood that if the just do what lies in their power, the Lord will deliver them. And these examples are brought forward so that we may know that the Lord has providence over all things, and gives to each according to its own manner: for to the birds he gave the means by which they might acquire necessities, for he gave them a natural instinct by which they are moved to seek out whence they might live; therefore we ought not to be excessively anxious. "But which of you by taking thought can add one cubit to his stature?" Here he proves by experience that just as he provides for the birds, so also for us: for there is a part of the soul that is subject to reason, such as the motive and sensitive powers, and a part that is not, such as the augmentative and nutritive powers; and in these man agrees with brute animals; and just as he provides for brute animals in growth and nourishment, so also for men. Hence growth is not from ourselves, but from God; hence you ought not to despair of God's providence. "Consider the lilies of the field," and so on. He has instructed us concerning food, now concerning clothing; hence, "having food, and something with which to be covered, with these we are content." He says, therefore, "Consider the lilies of the field." The consideration of creatures ought to be for the praise of God; Psalm 142:5: "I will meditate on all your works," and so on. "They labor not, neither do they spin": for both the work of men and of women is required for clothing; therefore, to remove the work of men he says, "they labor not"; to exclude the work of women he says, "neither do they spin." For I say to you that "not even Solomon in all his glory was arrayed as one of these," because even though art imitates nature, it nevertheless does not attain to it. Hence art would never produce colors as pure as those that occur in nature in the flowers. And he says "in glory," because among those known among the Jews, Solomon was more glorious; and yet clothing could not be so fitted to him as it is to the lily. Again, Chrysostom says that the lily has these things without anxiety, whereas Solomon at least had to give orders for his. Jerome turns this back to the resurrection, since by the lilies are meant the angels; and just as angels have no need of clothing, so in the resurrection he who will refashion the body will provide for its clothing. "For if the grass of the field," and so on. Here he changes the lily into grass, and argues that if God provides for the lesser things, he will provide also for us, who are of greater worth as to the dignity of our substance, since we are above these things. Again, as to duration: since we are eternal as to the soul, whereas this grass "today is, and tomorrow is cast into the oven," and so on; Isaiah 40:7: "The grass is withered, and the flower has fallen." Again, as to the end: because man exists for the sake of beatitude, whereas grass exists for the use of man; Psalm 146:8: "Who brings forth grass and herb on the mountains for the service of men," and so on — and for a base use at that, namely that it be cast into the oven, with respect to certain lands, where fire is made from stubble. "And if God so clothes" this, that is, gives it its necessary adornment, "how much more you, of little faith?" Or thus: that by the grass are understood unbelievers — if then God provides for unbelievers, who are ready for the oven of fire, much more will he provide for the elect. "Be not therefore anxious," and so on. Here he draws his conclusion concerning both food and clothing; and you should explain "anxiety" in the four ways stated above. Or thus: if you live within some community, do not be anxious for more abundant food or more abundant clothing, but rather be among them as one of them. "For after all these things do the Gentiles seek," because they place their end there, since they believe that beatitude consists in them; and if they do not believe this, they still place great anxiety there, because they do not believe in divine providence. And because in ordering something toward an end two things are required, namely knowledge and will, he says, "For your Father knows that you need all these things." Hence: he knows, because he is God; likewise, because he is Father, he wills [to provide]. What then will you do? He states three things. First: "Seek the kingdom of God," as an end, since the kingdom is beatitude. The kingdom is named from ruling: for a man is then ruled when he is made subject to the will of the one ruling; but this will be in heaven; hence Luke 14:15: "Blessed is he who eats bread in the kingdom of God." Again, justice leads to the kingdom; Proverbs 8:20: "I walk in the ways of justice, in the midst of the paths of judgment, that I may enrich those who love me, and may fill their treasures," and so on. And therefore he says, "and his justice." And he says "his," and not "man's," because by his own justice no one can come to the kingdom. Third, he says, "and all these things will be added unto you," as if to say, beyond the bargain these things will be added; Proverbs 10:3: "The Lord will not afflict the soul of the just with famine." We ought not, therefore, to seek these temporal things — and this is true if they are sought as an end, or as a reward. Hence we ought not to preach the gospel in order that we may eat, but rather the reverse. But against this Augustine raises an objection concerning Paul, since he says: "In hunger, and thirst, and nakedness I have labored." And he answers that just as a physician sometimes withholds food and drink from a sick person, in order to cure him, so the Lord, whose task it is to provide, permits a man to suffer, either that he may be cured, if there is something to be cured, or that others may receive an example. "Be not therefore anxious for tomorrow." But this does not seem right, because no one is bound to a greater perfection than Christ and the apostles; but Christ had a money-box, and the apostles too used to gather provisions. Augustine explains it thus: "for tomorrow," that is, for the future, meaning: by thinking too much about temporal things, namely by placing one's end there, or also by gathering superfluous things. Or, according to Jerome, "Be not anxious for tomorrow" is true concerning those things which pertain to God, provided we are doing what lies in our power; for we ought not to cease from laboring for fear of rain, or such other things which pertain to God. Or thus: do not take up in the present that anxiety which you ought to have in the future, just as it is not fitting, at the time of the harvest, to take up care about the vintage. Why? For "sufficient for the day is its own evil" — that is, the tribulation and anguish which a man has in his day ought to suffice for him; he ought not to take up in advance that which he is to have in the future, and so on.”

“Worldly-mindedness is as common and as fatal a symptom of hypocrisy as any other, for by no sin can Satan have a surer and faster hold of the soul, under the cloak of a visible and passable profession of religion, than by this; and therefore Christ, having warned us against coveting the praise of men, proceeds next to warn us against coveting the wealth of the world; in this also we must take heed, lest we be as the hypocrites are, and do as they do: the fundamental error that they are guilty of is, that they choose the world for their reward; we must therefore take heed of hypocrisy and worldly-mindedness, in the choice we make of our treasure, our end, and our masters. I. In choosing the treasure we lay up. Something or other every man has which he makes his treasure, his portion, which his heart is upon, to which he carries all he can get, and which he depends upon for futurity. It is that good, that chief good, which Solomon speaks of with such an emphasis, Ecc 2:3. Something the soul will have, which it looks upon as the best thing, which it has a complacency and confidence in above other things. Now Christ designs not to deprive us of our treasure, but to direct us in the choice of it; and here we have, 1. A good caution against making the things that are seen, that are temporal, our best things, and placing our happiness in them. Lay not up for yourselves treasures upon earth. Christ's disciples had left all to follow him, let them still keep in the same good mind. A treasure is an abundance of something that is in itself, at least in our opinion, precious and valuable, and likely to stand us in stead hereafter. Now we must not lay up our treasures on earth, that is, (1.) We must not count these things the best things, nor the most valuable in themselves, nor the most serviceable to us: we must not call them glory, as Laban's sons did, but see and own that they have no glory in comparison with the glory that excelleth. (2.) We must not covet an abundance of these things, nor be still grasping at more and more of them, and adding to them, as men do to that which is their treasure, as never knowing when we have enough. (3.) We must not confide in them for futurity, to be our security and supply in time to come; we must not say to the gold, Thou art my hope. (4.) We must not content ourselves with them, as all we need or desire: we must be content with a little for our passage, but not with all for our portion. These things must not be made our consolation (Luk 6:24), our good things, Luk 16:25. Let us consider we are laying up, not for our posterity in this world, but for ourselves in the other world. We are put to our choice, and made in a manner our own carvers; that is ours which we lay up for ourselves. It concerns thee to choose wisely, for thou art choosing for thyself, and shalt have as thou choosest. If we know and consider ourselves what we are, what we are made for, how large our capacities are, and how long our continuance, and that our souls are ourselves, we shall see it is foolish thing to lay up our treasures on earth. 2. Here is a good reason given why we should not look upon any thing on earth as our treasure, because it is liable to loss and decay: (1.) From corruption within. That which is treasure upon earth moth and rust do corrupt. If the treasure be laid up in fine clothes, the moth frets them, and they are gone and spoiled insensibly, when we thought them most securely laid up. If it be in corn or other eatables, as his was who had his barns full (Luk 12:16, Luk 12:17), rust (so we read it) corrupts that: brōsis - eating, eating by men, for as goods are increased they are increased that eat them (Ecc 5:11); eating by mice or other vermin; manna itself bred worms; or it grows mouldy and musty, is struck, or smutted, or blasted; fruits soon rot. Or, if we understand it of silver and gold, they tarnish and canker; they grow less with using, and grow worse with keeping (Jam 5:2, Jam 5:3); the rust and the moth breed in the metal itself and in the garment itself. Note, Worldly riches have in themselves a principal of corruption and decay; they wither of themselves, and make themselves wings. (2.) From violence without. Thieves break through and steal. Every hand of violence will be aiming at the house where treasure is laid up; nor can any thing be laid up so safe, but we may be spoiled of it. Numquam ego fortunae credidi, etiam si videretur pacem agere; omnia illa quae in me indulgentissime conferebat, pecuniam, honores, gloriam, eo loco posui, unde posset ea, since metu meo, repetere - I never reposed confidence in fortune, even if she seemed propitious: whatever were the favours which her bounty bestowed, whether wealth, honours, or glory, I so disposed of them, that it was in her power to recall them without occasioning me any alarm. Seneca. Consol. ad Helv. It is folly to make that our treasure which we may so easily be robbed of. 3. Good counsel, to make the joys and glories of the other world, those things not seen that are eternal, our best things, and to place our happiness in them. Lay up for yourselves treasures in heaven. Note, (1.) There are treasures in heaven, as sure as there are on this earth; and those in heaven are the only true treasures, the riches and glories and pleasures that are at God's right hand, which those that are sanctified truly arrive at, when they come to be sanctified perfectly. (2.) It is our wisdom to lay up our treasure in those treasures; to give all diligence to make sure our title to eternal life through Jesus Christ, and to depend upon that as our happiness, and look upon all things here below with a holy contempt, as not worthy to be compared with it. We must firmly believe there is such a happiness, and resolve to be content with that, and to be content with nothing short of it. If we thus make those treasures ours, they are laid up, and we may trust God to keep them safe for us; thither let us then refer all our designs, and extend all our desires; thither let us send before our best efforts and best affections. Let us not burthen ourselves with the cash of this world, which will but load and defile us, and be liable to sink us, but lay up in store good securities. The promises are bills of exchange, by which all true believers return their treasure to heaven, payable in the future state: and thus we make that sure that will be made sure. (3.) It is a great encouragement to us to lay up our treasure in heaven, that there it is safe; it will not decay of itself, no moth nor rust will corrupt it; nor can we be by force or fraud deprived of it; thieves do not break through and steal. It is a happiness above and beyond the changes and chances of time, an inheritance incorruptible. 4. A good reason why we should thus choose, and an evidence that we have done so (Mat 6:21), Where your treasure is, on earth or in heaven, there will you heart be. We are therefore concerned to be right and wise in the choice of our treasure, because the temper of our minds, and consequently the tenor of our lives, will be accordingly either carnal or spiritual, earthly or heavenly. The heart follows the treasure, as the needle follows the loadstone, or the sunflower the sun. Where the treasure is there the value and esteem are, there the love and affection are (Col 3:2), that way the desires and pursuits go, thitherward the aims and intents are levelled, and all is done with that in view. Where the treasure is, there our cares and fears are, lest we come short of it; about that we are most solicitous; there our hope and trust are (Pro 18:10, Pro 18:11); there our joys and delights will be (Psa 119:111); and there our thoughts will be, there the inward thought will be, the first thought, the free thought, the fixed thought, the frequent, the familiar thought. The heart is God's due (Pro 23:26), and that he may have it, our treasure must be laid up with him, and then our souls will be lifted up to him. This direction about laying up our treasure, may very fitly be applied to the foregoing caution, of not doing what we do in religion to be seen of men. Our treasure is our alms, prayers, and fastings, and the reward of them; if we have done these only to gain the applause of men, we have laid up this treasure on earth, have lodged it in the hands of men, and must never expect to hear any further of it. Now it is folly to do this, for the praise of men we covet so much is liable to corruption: it will soon be rusted, and moth-eaten, and tarnished; a little folly, like a dead fly, will spoil it all, Ecc 10:1. Slander and calumny are thieves that break through and steal it away, and so we lose all the treasure of our performances; we have run in vain, and laboured in vain, because we misplaced our intentions in doing of them. Hypocritical services lay up nothing in heaven (Isa 58:3); the gain of them is gone, when the soul is called for, Job 27:8. But if we have prayed and fasted and given alms in truth and uprightness, with an eye to God and to his acceptance, and have approved ourselves to him therein, we have laid up that treasure in heaven; a book of remembrance is written there (Mal 3:16), and being there recorded, they shall be there rewarded, and we shall meet them again with comfort on the other side death and the grave. Hypocrites are written in the earth (Jer 17:13), but God's faithful ones have their names written in heaven, Luk 10:20. Acceptance with God is treasure in heaven, which can neither be corrupted nor stolen. His well done shall stand for ever; and if we have thus laid up our treasure with him, with him our hearts will be; and where can they be better? II. We must take heed of hypocrisy and worldly-mindedness in choosing the end we look at. Our concern as to this is represented by two sorts of eyes which men have, a single eye and an evil eye, Mat 6:22, Mat 6:23. The expressions here are somewhat dark because concise; we shall therefore take them in some variety of interpretation. The light of the body is the eye, that is plain; the eye is discovering and directing; the light of the world would avail us little without this light of the body; it is the light of the eye that rejoiceth the heart (Pro 15:30), but what is that which is here compared to the eye in the body. 1. The eye, that is, the heart (so some) if that be single - haplous - free and bountiful (so the word is frequently rendered, as Rom 12:8; Co2 8:2, Co2 9:11, Co2 9:13; Jam 1:5, and we read of a bountiful eye, Pro 22:9). If the heart be liberally affected and stand inclined to goodness and charity, it will direct the man to Christian actions, the whole conversation will be full of light, full of evidences and instances of true Christianity, that pure religion and undefiled before God and the Father (Jam 1:27), full of light, of good works, which are our light shining before men; but if the heart be evil, covetous, and hard, and envious, griping and grudging (such a temper of mind is often expressed by an evil eye, Mat 20:15; Mar 7:22; Pro 23:6, Pro 23:7), the body will be full of darkness, the whole conversation will be heathenish and unchristian. The instruments of the churl are and always will be evil, but the liberal deviseth liberal things, Isa 32:5-8. If the light that is in us, those affections which should guide us to that which is good, be darkness, if these be corrupt and worldly, if there be not so much as good nature in a man, not so much as a kind disposition, how great is the corruption of a man, and the darkness in which he sits! This sense seems to agree with the context; we must lay up treasure in heaven by liberality in giving alms, and that not grudgingly but with cheerfulness, Luk 12:33; Co2 9:7. But these words in the parallel place do not come in upon any such occasion, Luk 11:34, and therefore the coherence here does not determine that to be the sense of them. 2. The eye, that is, the understanding (so some); the practical judgment, the conscience, which is to the other faculties of the soul, as the eye is to the body, to guide and direct their motions; now if this eye be single, if it make a true and right judgment, and discern things that differ, especially in the great concern of laying up the treasure so as to choose aright in that, it will rightly guide the affections and actions, which will all be full of the light of grace and comfort; but if this be evil and corrupt, and instead of leading the inferior powers, is led, and bribed, and biassed by them, if this be erroneous and misinformed, the heart and life must needs be full of darkness, and the whole conversation corrupt. They that will not understand, are said to walk on in darkness, Psa 82:5. It is sad when the spirit of a man, that should be the candle of the Lord, is an ignis fatuus: when the leaders of the people, the leaders of the faculties, cause them to err, for then they that are led of them are destroyed, Isa 9:16. An error in the practical judgment is fatal, it is that which calls evil good and good evil (Isa 5:20); therefore it concerns us to understand things aright, to get our eyes anointed with eye-salve. 3. The eye, that is, the aims and intentions; by the eye we set our end before us, the mark we shoot at, the place we go to, we keep that in view, and direct our motion accordingly; in every thing we do in religion; there is something or other that we have in our eye; now if our eye be single, if we aim honestly, fix right ends, and move rightly towards them, if we aim purely and only at the glory of God, seek his honor and favour, and direct all entirely to him, then the eye is single; Paul's was so when he said, To me to live is Christ; and if we be right here, the whole body will be full of light, all the actions will be regular and gracious, pleasing to God and comfortable to ourselves; but if this eye be evil, if, instead of aiming only at the glory of God, and our acceptance with him, we look aside at the applause of men, and while we profess to honour God, contrive to honour ourselves, and seek our own things under colour of seeking the things of Christ, this spoils all, the whole conversation will be perverse and unsteady, and the foundations being thus out of course, there can be nothing but confusion and every evil work in the superstructure. Draw the lines from the circumference to any other point but the centre, and they will cross. If the light that is in thee be not only dim, but darkness itself, it is a fundamental error, and destructive to all that follows. The end specifies the action. It is of the last importance in religion, that we be right in our aims, and make eternal things, not temporal, our scope, Co2 4:18. The hypocrite is like the waterman, that looks one way and rows another; the true Christian like the traveller, that has his journey's end in his eye. The hypocrite soars like the kite, with his eye upon the prey below, which he is ready to come down to when he has a fair opportunity; the true Christian soars like the lark, higher and higher, forgetting the things that are beneath. III. We must take heed of hypocrisy and worldly-mindedness in choosing the master we serve, Mat 6:24. No man can serve two masters. Serving two masters is contrary to the single eye; for the eye will be to the master's hand, Psa 123:1, Psa 123:2. Our Lord Jesus here exposes the cheat which those put upon their own souls, who think to divide between God and the world, to have a treasure on earth, and a treasure in heaven too, to please God and please men too. Why not? says the hypocrite; it is good to have two strings to one's bow. They hope to make their religion serve their secular interest, and so turn to account both ways. The pretending mother was for dividing the child; the Samaritans will compound between God and idols. No, says Christ, this will not do; it is but a supposition that gain is godliness, Ti1 6:5. Here is, 1. A general maxim laid down; it is likely it was a proverb among the Jews, No man can serve two masters, much less two gods; for their commands will some time or other cross or contradict one another, and their occasions interfere. While two masters go together, a servant may follow them both; but when they part, you will see to which he belongs; he cannot love, and observe, and cleave to both as he should. If to the one, not to the other; either this or that must be comparatively hated and despised. This truth is plain enough in common cases. 2. The application of it to the business in hand. Ye cannot serve God and Mammon. Mammon is a Syriac word, that signifies gain; so that whatever in this world is, or is accounted by us to be, gain (Phi 3:7), is mammon. Whatever is in the world, the lust of the flesh, the lust of the eye, and the pride of life, is mammon. To some their belly is their mammon, and they serve that (Phi 3:19); to others their ease, their sleep, their sports and pastimes, are their mammon (Pro 6:9); to others worldly riches (Jam 4:13); to others honours and preferments; the praise and applause of men was the Pharisees' mammon; in a word, self, the unity in which the world's trinity centres, sensual, secular self, is the mammon which cannot be served in conjunction with God; for if it be served, it is in competition with him and in contradiction to him. He does not say, We must not or we should not, but we cannot serve God and Mammon; we cannot love both (Jo1 2:15; Jam 4:4); or hold to both, or hold by both in observance, obedience, attendance, trust, and dependence, for they are contrary the one to the other. God says, "My son, give me thy heart." Mammon says, "No, give it me." God says, "Be content with such things as ye have." Mammon says, "Grasp at all that ever thou canst. Rem, rem, quocunque modo rem - Money, money; by fair means or by foul, money." God says, "Defraud not, never lie, be honest and just in all thy dealings." Mammon says "Cheat thine own Father, if thou canst gain by it." God says, "Be charitable." Mammon says, "Hold thy own: this giving undoes us all." God says, "Be careful for nothing." Mammon says, "Be careful for every thing." God says, "Keep holy thy sabbath-day." Mammon says, "Make use of that day as well as any other for the world." Thus inconsistent are the commands of God and Mammon, so that we cannot serve both. Let us not then halt between God and Baal, but choose ye this day whom ye will serve, and abide by our choice.”

“Lay not up for yourselves treasures upon earth,.... Meaning either treasures that are of an earthly nature and kind, the more valuable and excellent things of the earth, worldly wealth and riches; or the things and places, in which these are laid up, as bags, chests, or coffers, barns and other treasuries, private or public. Christ here dissuades from covetousness, and worldly mindedness; an anxious care and concern, to hoard up plenty of worldly things for themselves, for time to come, making no use of them at present for the good of others: and this he does, from the nature of the things themselves; the places where they are laid up; the difficulty of keeping them; and their liableness to be corrupted or lost. Where moth and rust doth corrupt, and thieves break through and steal. Garments, formerly, were a considerable part of the treasures of great men, as well as gold and silver; see Job 27:16. So according to the (m) Targumist, Haman is bid to go , "to the king's treasury", and take from thence one of the purple garments, the best, and raiment of the best silk, &c. and these were liable to be eaten with the moth, Jam 5:2. The word translated rust, does not here signify the rust of metals, as gold and silver; by which there is not so much damage done, so as to destroy them, and make them useless; but whatever corrupts and consumes things eatable, as blasting and mildew in corn, or any sort of vermin in granaries: for gold and silver, or money, with jewels and precious stones, which make a very great part of worldly treasure, seem to be more particularly designed, by what thieves break through into houses for, and carry away. So that here are three sorts of earthly treasures pointed at, which are liable to be corrupted, or taken away: garments, which may be destroyed, and rendered useless for wearing; provisions of things eatable, as all sorts of corn and grain, which may be so corrupted by smut and vermin, as not to be fit for use; and money and jewels, which may be stolen by thieves: so that no sort of worldly riches and treasure is safe, and to be depended on; and therefore it is a great folly and vanity to lay it up, and trust in it. (m) Targum Sheni. in Esth. vi. 10.”

“CONCLUDING ILLUSTRATIONS OF THE RIGHTEOUSNESS OF THE KINGDOM--HEAVENLY-MINDEDNESS AND FILIAL CONFIDENCE. (Mat. 6:19-34) Lay not up for ourselves treasures upon earth--hoard not. where moth--a "clothes-moth." Eastern treasures, consisting partly in costly dresses stored up (Job 27:16), were liable to be consumed by moths (Job 13:28; Isa 50:9; Isa 51:8). In Jam 5:2 there is an evident reference to our Lord's words here. and rust--any "eating into" or "consuming"; here, probably, "wear and tear." doth corrupt--cause to disappear. By this reference to moth and rust our Lord would teach how perishable are such earthly treasures. and where thieves break through and steal--Treasures these, how precarious!”

“Otherwise; As the Lord had above taught nothing concerning alms, or prayer, or fasting, but had only checked a pretence of them, He now proceeds to deliver a doctrine of three portions, according to the division which He had before made, in this order. First, a counsel that alms should be done; second, to shew the benefit of almsgiving; third, that the fear of poverty should be no hindrance to our purpose of almsgiving.”
