“"Let waters from your own fountain flow in abundance for you, but let your waters pass through into your streets." And according to the prophet Isaiah, "You shall be like a watered garden and like a fountain of water whose waters shall not fail. And the places that have been desolate for ages shall be built in you; you shall raise up the foundations of generation and generation; and you shall be called the repairer of the fences, turning the paths into rest." And that blessedness shall come upon you which the same prophet promises: "And the Lord will not cause your teacher to flee away from you any more, and your eyes shall see your teacher. And your ears shall hear the word of one admonishing you behind your back. This is the way, walk in it, and go not aside either to the right hand or to the left." And so it will come to pass that not only every purpose and thought of our heart but also all the wanderings and rovings of your imagination will become to you a holy and unceasing pondering of the divine law.”

“Woe, sons. In this part the prophet threatens against those who despised the prophecy of Jeremiah, going into Egypt against his counsel, as is found in Jeremiah 43. And it is divided into two. In the first he threatens against the Jews alone; in the second against the Jews and the Egyptians together, in whom they trusted: chapter 31, Woe to those who go down. Or, according to the Gloss, in the first part he forbids the going down, in the second he threatens punishment against those going down. The first into two. In the first he sets forth the threat; in the second, consolation, therefore he waits. The first into two. In the first he reproves the going-down; second, the contempt of the divine precept, therefore I have cried out. Concerning the first he reproves three things in them. First, the disposition of the journey, setting forth their purpose, that you might take counsel ... a web, a wicked contrivance; and the resulting effect, that you might add: 2 Paralipomenon 28: Why do you wish to add sins upon sins? Second, he sets forth the execution of the plan as regards the going of the way, who walk; which is marred by the contempt of the divine counsel, my mouth, the prophet. Jeremiah 15: If you separate the precious from the vile, you shall be as my mouth: because what he said to do you were unwilling to do. And through confidence in human help, having confidence. Jeremiah 17: Cursed is the man who trusts in man, and makes flesh his arm. And he sets forth the effect: and it shall be to you, Hosea 4: I will change their glory into shame. Hence as to the terminus of the way — for they had gone into Tahpanhes, which is only in another part of Egypt — as though fearing to remain at the first borders. Jeremiah 2: What do you want in the way of Egypt, that you should drink muddy water? And he shows the failure of hope: they are all confounded. Psalm 145: Trust not in princes. Third, he describes the carrying away of goods, the burden of the beasts of burden, first threatening the destruction of Egypt: the burden of the sons of Judah. Of the beasts of burden, on account of their stupidity; or because, like beasts of burden, they carried their own goods. Of the south, because they fled toward the south, or because their dwelling was in the southern region. In the land of tribulation, in Egypt, which in Hebrew is called Mesraim, which is interpreted tribulation, or anguish. Jeremiah 42: The sword which you fear. Second, he sets forth the condition of those carrying the goods: lioness, on account of ferocity; lion, on account of the presumption of daring; viper, on account of cruelty; flying basilisk, not that it has wings, but because it leaps into a man's face, on account of its swiftness in doing harm. Sophonias 3: Her princes are like lions. Third, the carrying away of goods, carrying. Fourth, the frustration of their labor, to a people, Psalm 59: vain is the salvation of man. Therefore I have cried out. Here he reproves in them the contempt of God: and first he shows how they despised the divine precept; in the second how they despised salutary counsel, because thus says. Concerning the first he sets forth three things: first, God's precept; second, the people's contempt, for the people; third, he threatens death, or the ruin of death, to those who despise, therefore thus says. Concerning the first he sets forth three things. First, the precept: therefore — namely because it is useless — be still, in your land. Jeremiah 14: Thus says the Lord to this people, who have loved to move their foot, and have not rested, and have not pleased the Lord. Second, he sets forth the confirmation of the precept. Now therefore, you Isaiah, go in, into the prophetic vision, or you Jeremiah, go in, into Egypt with the people, as is read in Jeremiah 43. Third, he assigns the fruit of the confirmation, and it shall be in that day. Exodus 17: Write this for a memorial. The people. Here he sets forth the contempt of the people: and first insofar as they despised God. Unto wrath, as regards the sin of transgression. Ezechiel 2: Be not exasperating, as the house of Israel is an exasperating house. Lying, as regards the sin of speech, because they promised Jeremiah obedience, which they were unwilling to keep, as is found in Jeremiah 42. Psalm 17: Strange children have lied to me. Unwilling, as regards the sin of omission. Proverbs 28: He who stops his ear against hearing the law, his prayer shall be execrable. Second, he sets forth the contempt of the prophets, who say to the seers, insofar as they forbade them their proper office. Amos 7: You who see, go, flee. Insofar as they were leading them to falsehood, speak. 3 Kings, last chapter: Behold, the words of the prophets all foretell good things to the king. Turn aside, insofar as they forbade the word of divine knowledge. Job 21: Who have said to God: We wish not the knowledge of your ways. Therefore thus says. Here he threatens them with (sudden) ruin, resuming the fault so that the punishment may appear more just: because. But he adjoins the punishment, there, therefore this shall be to you; signifying a sudden punishment by the likeness of a ruin, which lies hidden long in a wall, which at last suddenly falls, because suddenly: 1 Thessalonians 5: For when they shall say, peace and security; then sudden destruction shall come upon them. And he also shows the punishment to be strong, and it shall be broken, under the likeness of the breaking of a flask, of which no shard remains whole for anything of use, namely for carrying fire, and for drawing water. Above, chapter 24: With breaking shall the earth be broken. Note on that word, be still, that man ought first to rest from the act of sin. Above, chapter 1: Cease to do perversely, learn to do well. Second, from the course of wandering. Jeremiah 14: You shall say this to this people, who have loved to move their feet, and have not rested. Third, from immoderate desire. Below, chapter 57: the heart of the wicked is like a raging sea, which cannot rest. Fourth, from a presumptuous intellect. Ecclesiasticus 18: When a man has finished, then shall he begin. For thus says the Lord. Here he reproves in them the contempt of the divine counsel: and concerning this he sets forth three things. First, the counsel: if you return. Below, chapter 45: Be converted to me, and you shall be saved. Second, the contempt: and you said. Therefore you shall flee: this is the word of the Lord. Deuteronomy 2: We will go by one way. And we will ride upon swift ones: the voice of the rebellious people. Therefore swifter ones: the voice of the Lord. Lamentations 4: Our persecutors were swifter than the eagles of the sky. Third, he threatens ruin: a thousand — the Egyptians; one — a Chaldean. You shall all flee — you Jews; five — of the Chaldeans. Deuteronomy 32: How should one pursue after a thousand, and two put ten thousand to flight? As a mast, as a sign for avoiding shipwreck. Above, chapter 6: It shall be for a show, like the turpentine tree, and like an oak that spreads its branches. Therefore he waits. Here he sets forth consolation: and concerning this he does two things. First he sets forth the purpose of having mercy; second he carries out the benefit of mercy, for the people. Concerning the first he sets forth three things. First, the purpose of having mercy in God, therefore he waits, not destroying you utterly. Hosea 3: You shall wait for me many days. Second, the judgment of the ungrateful: and therefore he shall be exalted; that is, he shall appear high in justice, punishing you who are ungrateful for his benefits. Above, chapter 5: The Lord of hosts shall be exalted in judgment. Third, the reward of the good, blessed are all. Luke 12: You like men who wait for their lord. For the people. Here he carries out the benefit of mercy: and first in their exaltation; second in the oppression of their enemies, behold the name. Concerning the first he sets forth two things. First, the removal of evils, against the captivity of exile. For the people, in the time of Zorobabel: or rather mystically, the whole. Psalm 124: He that dwells in Jerusalem shall not be moved forever. Against the anguish of sadness: weeping — earlier; you shall by no means weep — not forever, but until you are set free. Above, chapter 25: He shall take away the tear from every face. Against God's indignation, having mercy. Psalm 90: He shall call upon me, and I will hear him. Against poverty: and the Lord will give you. And the sense is: they shall be content with little food. Ecclesiasticus 29: The chief thing for man's life is bread and water. Or because in the return from Babylon they suffered want. Mystically, according to the Gloss. Second, he sets forth the bestowal of good things: hence, he will give. And first of spiritual things, as to chosen doctrine, describing the teacher: to fly away, to withdraw; the teacher — Esdras, whose doctrine they still use, or Christ; behind your back, like one fleeing when he is called back by one pursuing. Joel 2: The Lord has given you a teacher of justice. And he sets forth the doctrine: this is the way. Numbers 21: We will go by the king's highway. And also as to the due worship of God, and you shall pollute, that is, you shall reduce to common use. 4 Kings 23: He polluted the high places, and demolished them. The covering, all the ornament of the idol. Second, as to temporal goods: hence he says, go forth, namely from spiritual things to temporal, (O Isaiah or Jeremiah). And first he promises the fertility of the land, promising the cause: rain shall be given. Joel 2: He will cause the rain to come down to you. And the effect, as to the food of men. And bread of the grains. Genesis 49: Aser, his bread shall be fat. Psalm 147: He fills you with the fat of wheat. As to the pasture of herds: the lamb shall be fed, as to sheep; bulls, as to oxen; and in both he notes fruitfulness, setting down young ones. And the young of asses, as to the provender of beasts of burden; mash — barley cleared of chaff, which before they ate mixed together. Second, he promises abundance of waters, and there shall be. The Jews say these things are to be fulfilled literally at the end of the world — of many, of the Romans, according to them; which is fabulous. Or it can be a metaphorical expression: so that by water is signified the consolation which they had after the return from captivity and the destruction of Babylon. Or mystically, of the doctrine of Christ. Below, chapter 41: I will open rivers in the highest hills, and fountains in the midst of the plains. Third, the brightness of the sky, and the light of the sun shall be as the light of seven, that is, as much in one as now in seven, as it were sevenfold: or as it was in the first week of days. These things the Jews say fabulously, literally, in the time of golden Jerusalem. But it is better that it be referred to the future glory of the saints, after the renewal of the world. Or metaphorically and hyperbolically it may be referred to the state of the people. Psalm 146: Who heals the brokenhearted, and binds up their bruises. Note on that word, and bread of the grains, that the word of God is bread — first, narrow, on account of the difficulty of keeping it. Matthew 7: Narrow is the way that leads to life. Second, most abundant, on account of the usefulness of its fruit. Below, chapter 55: As the rain comes down from heaven, and drenches the earth, and it springs up, and does not return there anymore, so shall be the word that shall go forth from my mouth. Third, rich, on account of the sweetness of delight. Genesis 49: Aser, his bread shall be fat. Behold the name of the Lord. Here he consoles them from the punishment of their enemies: and concerning this he sets forth three things. First, the coming of the judge who punishes; second, the manner of the punishment, and he shall make heard; third, the place of the punishment, it is prepared. Concerning the first he sets forth three things. First, the coming: he comes, unto universal judgment; from afar, foretold long before by the prophets. Or: he comes unto the destruction of Sennacherib; from afar, from the height of his power. Or unto the destroying of the Babylonians, by the Medes coming from afar. Jeremiah 5: Behold I will bring upon you a nation from afar. The name of the Lord — the Son, as to the first exposition; or because it redounds to his own glory, as to the second and third. Second, he shows the zeal of the one who comes, setting forth wrath in the heart, by way of anthropopathy, burning fury. Fury is anger kindled. Now it is kindled either as to the vehemence of the desire for vengeance; and as to this he says, burning: or as to the quantity of the punishment; and as to this he says, heavy. Below, chapter 65: These were a smoke in my fury, a fire burning all the day. He also sets forth wrath in the mouth: his lips are filled with indignation, reproaching sins; devouring, by threatening torments. Above, chapter 11: With the breath of his lips he shall slay the wicked. He also sets forth wrath in the deed: his spirit, that is, his indignation, even to the midst of the neck, that is, he shall bring it even unto destruction. Above, chapter 8: The overflowing fury shall pass through Judah. Third, he sets forth the effect of the indignation on the evil: the destruction of nations. To destroy the nations. Psalm 72: Lord, in your city you shall bring their image to nothing. And the cessation of tyrants, and a bridle of error. Job 30: His quiver, etc. He also sets forth the effect on the good, in the praise of the mouth: there shall be a canticle of solemnity: because at the three solemn feasts they went up to Jerusalem with gladness. Leviticus 23; below, chapter 33: Your eyes shall see the city of our solemnity. And in the gladness of the heart, in the joy of the heart. Below, chapter 51: joy and gladness, etc. Judith, last chapter: And the people of the Lord was joyful. And he shall make heard. Here he describes the manner of the punishment: and concerning this he does three things. First, he describes the manner of the punishment as to the act of the one punishing. Of his voice, by which he shall appear glorious; and the terror of his arm, by the likeness of one enraged, who threatens in these ways. Job 40: If you have an arm like God. And as to the instrument, and the flame of fire: because, literally, the Assyrians were burned up. And perhaps there was some storm. Or diverse punishments in the day of judgment are signified. Ecclesiasticus 30: fire, hail, etc. Psalm 148: Fire, hail, snow, ice, stormy winds. Second, he sets forth the infliction of the punishment, showing its horror, for at the voice; and the duration of the punishment, and the passage shall be founded, that is, made firm. Third, the exultation of the saints, with harps; in the chief battles, which are waged by divine power alone. Psalm 57: The just shall rejoice when he shall see the revenge. It is prepared. Here he describes the place of the punishment: and first its arrangement. Topheth, the valley of the son of Ennom, Gehenna, because fire was kept there for sacrifices, in stones from Tophet. It is the same valley as Gethsemani, in which the army of Sennacherib was destroyed. Or by it is signified Hell itself. Hence the Jews conjecture that Hell is there, because from two palm trees that are there, smoke is always sent forth. From yesterday, that is, from the beginning; or from the second day, according to the Jews, which had only yesterday: hence the day before yesterday. Concerning this valley it is found in Jeremiah 7 and 19. By the king, God. Above, chapter 5: Hell has enlarged its soul. Second, the diversity of punishments, the nourishment thereof. Wood — the wicked, or those of Sennacherib's army. Breath, that is, by will, metaphorically. Psalm 10: Fire, brimstone, and storms of winds, etc. Note on that word, behold the name of the Lord, that the Son of God is the name of the Father: first, by which he is made manifest. John 17: I have manifested your name to men. Second, by which he is honored. Matthew 6: Father, hallowed be your name. Third, by which he is invoked. John 16: Whatsoever you shall ask the Father in my name, he will give you. Again, on that word, he comes from afar, that he comes from afar, first, on account of the long expectation. Hebrews 11: All these died according to faith, not having received the promises, but beholding them afar off. Second, on account of the imperfection of our merits. Ephesians 2: Coming, he preached peace to you who were far off. Third, on account of the delay of time. Numbers 24: I shall see him, but not now; I shall behold him, but not near. Fourth, on account of the height of his majesty. Psalm 18: His going out is from the end of heaven, and his circuit even to the end thereof. Again, on that word, his tongue as fire, that charity is called fire: first because it illumines. Ecclesiasticus 2: You that fear God, love him, and your hearts shall be enlightened. Second, because it seethes. Canticle 2: Stay me up with flowers, compass me about with apples; because I languish with love. Third, because it turns all things to itself. Romans 8: We know that to them that love God, all things work together unto good. Fourth, because it makes ready. John 14: If anyone loves me, he will keep my word. Fifth, because it draws upward. Canticle 3: In my bed I sought him whom my soul loves; I sought him, and found him not. Note on that word, it is prepared, that Hell is wide: first, on account of the avidity of retaining, above, chapter 5: Hell has enlarged its soul; second, on account of the multitude of the damned, Matthew 7: Narrow is the way that leads to life; third, on account of the diversity of punishments, Psalm 148: fire, hail, snow, ice, etc., or Psalm 10: fire, brimstone and storms, etc.; fourth, on account of the eternity of the punishment, Matthew 25: Depart, you cursed, into everlasting fire.”

“And though the Lord give you the bread of adversity, and the water of affliction,.... Either at this present time, when the city was besieged by Sennacherib; or when it should be besieged by the Chaldeans, when adversity was their bread, and affliction their water; or when they had only bread and water in their adversity and affliction; or a famine of bread and water, as is common in times of a siege. It may refer to the poor, and mean, and afflicted state of the people of God, in the first times of the Gospel especially: yet shall not thy teachers be removed into a corner any more; or, "thy rain" (b), as some interpret it; one and the same word signifies both rain and a teacher, because doctrine from the mouth of a teacher drops like rain upon the tender herb, and as showers on the grass; and is to be understood, not merely in a literal sense, of rain, and fruitfulness by it, in opposition to penury and famine for want of it; but of rain of spiritual doctrine; and so the sense is much the same as if it was rendered teachers; that though the people of God should be attended with afflictions, yet they should have spiritual consolation; and though they might have a famine of bread and water, yet not of hearing the word of the Lord; their teachers should not be removed from them, as they had formerly been, perhaps in the time of Ahaz: or "take wing" (c), and fly away from them, as the word signifies, being scared by persecutors; so the prophets in the time of Ahab were forced to fly, and were hid by fifty in a cave. The word here used has in the Arabic language the signification of hiding, as Maimonides (d) from Aben Ganach has observed; and so may be read, "thy teachers shall not be hidden any more"; things being hidden under wings; see Psa 17:8, but thine eyes shall see thy teachers; in their proper place, doing the work of their office: it denotes not a bare seeing them with their bodily eyes, but a seeing them with pleasure and delight, a wistfully looking at them, and a diligent and attentive observance of what they said. Some understand these teachers of Hezekiah and his princes, as Aben Ezra, Kimchi, and Abendana; others of the priests and prophets in his time, the principal of which was Isaiah; others of the prophets a little before, in, and after the Babylonish captivity; it may be applied to John the Baptist, Christ, and his apostles, and other Gospel ministers. Jarchi interprets it of God himself, who teaches to profit, and who would not hide his face from his people; the Targum, of the Shechinah not removing from the sanctuary, but being seen there; and being in the plural number, may denote all the three Persons. (b) "pluvia tua", some in Munster, Calvin; so Ben Melech interprets it; and the same in the next clause. (c) "non avolabit", Piscator; "ad verb. alabitur", Forerius. (d) More Nevochim, par. 1. cap. 43. p. 61. So "operuit, sub alis tutatus est", Castel. col. 1760.”
