Isaiah 49:18 Douay-Rheims

Lift up thy eyes round about, and see all these are gathered together, they are come to thee: I live, saith the Lord, thou shalt be clothed with all these as with an ornament, and as a bride thou shalt put them about thee.

“We have often said already that blessed Job stands for a type of Holy Church. But all they, who are joined to it by the unity of the Faith, are the garments of the Church. Of which the Lord says to the same Church by the Prophet, "As I live, thou shall be clothed with all these, as with an ornament." But by the south wind, which is doubtless warm, is designated, not improperly, the Holy Spirit, for when any one is touched by It, he is freed from the torpor of his iniquity. The garments, therefore, of Holy Church are warm, while the earth is breathed upon by the south wind; because they, who cling to her by faith, glow with fervent zeal of charity, while their mind is streamed through by the breath of the Holy Spirit.”

“All of them. All of thy children. R. Moses Hakkohen explains the expression thus: Thy children as well as thy destroyers, that is, the wicked, gathered themselves, etc. According to this explanation the future יֵצֵאוּ is used instead of the past יׇצׇאוּ. But it is not necessary to assume this irregularity here. As I live. The decree shall not be annulled; as truly as I am living, it will be acted upon. כקשורי כלה = ככלה As the ornament of the bride round her neck.”

“Hear, O islands, etc. In this part he pursues the order of the liberation more specifically; and concerning this he does two things. First the people confesses the benefits received; second it receives the promise of things to come, there, I said: in vain, etc. Concerning the first, four benefits are confessed. First, the privilege of the divine election; and it continues why the prophet had above enjoined the people, that they should announce it. Whence immediately is subjoined the voice of the people announcing, and saying, Hear. From the womb, choosing me in the fathers themselves. Ps. 21: From the womb of my mother, God, etc. Second, the efficacy of prayer: and he set the mouth, prayer, as a sword, penetrating even to the ears of God and the depths of his mercy, Eph. ult.: the sword of the spirit, etc. Third, the help of divine protection: in the shadow, that is, under the protection of his power, as an archer hides a chosen arrow, to preserve it. Ps. 16: under the shadow of thy wings, etc.; Ps. 26: he hath hidden me in his tabernacle, etc. Fourth, the glory of the divine power: and he said to me: in thee will I glory; through the great things shown in thee I will appear glorious. Above, 43: every one that calleth upon my name, etc. According to others, this is the voice of Cyrus, whose name was foretold by Isaiah above, 45, before he was born; whose threatening words were as a sword, and he was protected lest his grandfather should kill him, and was kept as a chosen arrow for the appointed time; to whom it was announced that the people of Israel was the servant of God. Otherwise it is expounded of Christ; whose name was foretold by the Angel; the word of preaching, a sword piercing hearts; protected, on account of the weakness of the flesh, by the power of the divinity, and chosen among all for the fulfilling of the salvation of the human race. And he is called Israel, because he was born of the people of Israel according to the flesh. I said: here the Lord promises future benefits: and first he promises the prophet Isaiah exaltation; second, to the people liberation, there, thus saith the Lord the redeemer, etc. Concerning the first, two things. First is set down the allegation of the prophet, setting forth his labor in preaching, although through the fault of the hearers no fruit followed: and he concludes: therefore my judgment, on my behalf, is with the Lord, before him, and my work, as pleasing to him. Jer. 6: the founder hath melted in vain, etc. Second, he sets down God's response: and now thus saith the Lord: and first is signified the acceptance of the allegation, that I may bring back, as if to say: choosing me from the womb of my mother for this, that I might recall his people to him. And yet Israel shall not altogether be gathered, to him through my preaching. And yet I am glorified, etc.; Habac. 3: God, the Lord, is my strength, etc. Second, the response itself is set down, and he said: it is a small thing, as if to say: so greatly will I honor thy ministry that not only among the Jews, but among all the nations, my salvation shall be announced through thee. Rom. 3: is he the God of the Jews only? etc. This too is plainly expounded of Christ, who by his preaching and the consummation of his death made little fruit among the Jews, but enlightened and saved the nations. Likewise also of Cyrus, though more forcedly, who through his kindnesses, according to the Lord's intention, recalled the people to the worship of God, and yet did not succeed, to whom dominion over many nations was given by God. Thus saith the Lord the redeemer, etc. Here he promises liberation: and concerning this he does two things. First he promises liberation; second he excludes their doubt, there, and Sion said, etc. Concerning the first, three things. First, the things preceding liberation, namely the veneration of the Jews, which was the cause of the liberation; recalling their former contempt: contemptible, on account of the people's weakness; abominable, on account of the singularity of their worship; a servant, on account of subjection to diverse nations, above, 18: to a nation rent asunder, etc.; and he sets down the veneration itself: kings shall see the great things I will show for thee, and shall adore, as, according to the letter, Nabuchodonosor, Dan. 2, and Cyrus, and his other princes honored Esdras. Another preamble is the exaltation of the liberating king, namely Cyrus: in an acceptable time, and he does not determine the time of the exaltation: acceptable, when it shall please me to save my people, I have heard, exalting thee into a kingdom, according to thy desire, and the fruit of the exaltation: and I have preserved, etc., for the fulfilling of the covenant of my people. Be revealed, that is, be enlightened. Or of Christ, who in his passion was despised, and judged as it were a servant. Below, 53: we saw him despised, etc., but afterward, according to the letter, adored by kings. Ps. 71: all kings shall adore him, etc.; in an acceptable time, namely the time of grace. 2 Cor. 6: behold, now is the time, etc. Second, he sets down the things consequent upon the liberation, promising to the liberated an abundance of good things: they shall feed in the ways; that is, they shall enjoy consolations as abundantly as sheep enjoy pastures, when they are found even in the way, beyond the usual. Ezech. 34: they shall rest in the grass, etc.; as to the absence of evils, both of want, he shall not hunger, etc., and of harm inflicted, the heat, of tribulation; and the sun, the tyrant causing it. Ps. 120: the sun shall not burn by day, etc.; and he assigns the cause of both. Because he that is merciful, etc.; of waters, of consolations. Ps. 22: the Lord ruleth me. Third, he promises the liberation itself, setting down the preparation of the ways: and I will make all the mountains; that is, the princes will help you to return. Above, 40: every valley shall be filled, etc.; setting down also the return of the captives: behold these from afar, from the east, the sea, the west. Jer. 31: I will bring them from the north, etc.; he sets down also the giving of thanks: praise, ye heavens, etc.; Ps. 68: let the heavens praise him, etc. And Sion said, etc. Here he excludes their doubt: and first that which arose from the divine indignation; second that which arose from their dejection, there, and thou shalt say in the heart, etc.; third that which arose from the power of the enemies, there, shall it be taken away, etc. Concerning the first, two things. First he sets down the doubt: hath forsaken, without help; and therefore I cannot hope for liberation. Baruch 4: I am forsaken, etc.; second he excludes it by the likeness of a mother: is it possible, etc.; Jer. 31: if a son honorable, etc.; third he applies the promise concerning the restoration of the city: and first as to the rebuilding of the walls, setting down the divine purpose: behold, in my hands; as if to say: thus I hold thee in memory, as one who writes, or makes some sign on his hand, that he may be mindful of some thing. Thy walls; as if to say, now I see the rebuilding of thy walls. Job 37: he hideth in the hands, etc.; Ps. 89: a thousand years before the eyes, etc.; and the manner of the fulfillment: builders have come, that is, rebuilders, namely Zorobabel, and Jesus, and others, already in my eyes; the scatterers, the Chaldeans. Zach. 4: the hands of Zorobabel, etc. Second, as to the habitation of men: and concerning this he does three things. First, the gathering together of the citizens: lift up round about, etc.; Baruch 4: look about, Jerusalem, etc. Second, the re-inhabiting of the city, showing that it shall be inhabited. As I live, the manner of an oath; as with an ornament — as a bride with garments, so the city is adorned with citizens. Below, 61: he hath clothed me with the garment of salvation, etc.; showing that it shall be filled with inhabitants: for the desert places, as to inhabitants, the solitudes, as to the tillers, the ruins, as to the destroyed walls. Zach. 2: it shall be inhabited without a wall, etc.; he shows also that it shall be emptied of enemies: and far, etc. Third, he foretells the multitude of the inhabitants: still shall the children of sterility say, that is, those who were born when thou didst believe thyself barren, emptied of inhabitants. Below, 54: enlarge the place of the tent, etc. And thou shalt say in the heart, etc. Here he excludes the second doubt: and first he sets down the wonder, and thou shalt say, out of wonder: barren, because there were not in me men who could beget children; destitute, of divine help. Below, 66: who hath ever heard such, etc. Second he excludes the doubt, setting down the manner of the multitude of the inhabitants: thus saith the Lord: as to four things. First, as to the divine inspiration: behold I will lift up the hand, as it were making a sign; above, 11: he shall lift up a sign among the nations, etc. Second, as to the honorable bringing back: and they shall bring in the arms, in which is signified the help which they had from the nations. Kings, foster-fathers, providing for thee in necessities. Baruch 5: the Lord will bring them to thee, etc. Third, as to the exaltation of the liberated: with the face to the earth, this especially at the time of the Machabees; below, 40: they shall come to thee bowed down, etc. Fourth, he assigns the reason for this: and thou shalt know that I, etc.; Ps. 70: in thee, O Lord, have I hoped, let me not be confounded, etc. Shall it be taken away. Here he excludes the third doubt: and first he sets it down, from the strong, Nabuchodonosor; Matth. 12: or how can one enter, etc. Second he excludes it: for thus he saith, first setting down the benefit of the liberation: the captivity, namely of the Jews. Job 29: I broke the jaws of the wicked one, etc.; second, the manner of the liberation, setting down the destruction of the enemies. But them, namely the Chaldeans, they judged, unjustly. Soph. 3: I will kill, etc.; and he sets down the determination of the punishment: and I will feed: either on account of dissension, as above, 9: every man the flesh of the arm, etc., or on account of the multitude of the dead, while the mouth of one fell upon the blood of another, as if he would drink: or on account of famine. Third, he sets down the fruit of the liberation: and all flesh shall know, etc.; above, 40: all flesh shall see, etc.”

“Two things are here promised, which were to be in part accomplished in the reviving of the Jewish church after its return out of captivity, but more fully in the planting of the Christian church by the preaching of the gospel of Christ; and we may take the comfort of these promises. I. That the church shall be replenished with great numbers added to it. It was promised (Isa 49:17) that her children should make haste; that promise is here enlarged upon, and is made very encouraging. It is promised, 1. That multitudes shall flock to the church from all parts. Look round, and see how they gather themselves to thee (Isa 49:18), by a local accession to the Jewish church. They come to Jerusalem from all the adjacent countries, for that was then the centre of their unity; but, under the gospel, it is by a spiritual accession to the mystical body of Christ in faith and love. Those that come to Jesus as the Mediator of the new covenant do thereby come to the Mount Zion, the church of the first-born, Heb 12:22, Heb 12:23. Lift up thy eyes, and behold how the fields are white unto the harvest, Joh 4:35. Note, It is matter of joy to the church to see a multitude of converts to Christ. 2. That such as are added to the church shall not be a burden and blemish to her, but her strength and ornament. This part of the promise is confirmed with an oath: As I live, saith the Lord, thou shalt surely clothe thyself with them all. The addition of such numbers to the church shall complete her clothing; and, when all that were chosen are effectually called, then the bride, the Lamb's wife, shall have made herself ready, shall be quite dressed, Rev 19:7. They shall make her to appear comely and considerable; and she shall therefore bind them on with as much care and complacency as a bride does her ornaments. When those that are added to the church are serious, and holy, and exemplary in their conversation, they are an ornament to it. 3. That thus the country which was waste and desolate, and without inhabitant (Isa 5:9; Isa 6:11), shall be again peopled, nay, it shall be over-peopled (Isa 49:19): "Thy waste and thy desolate places, that have long lain so, and the land of thy destruction, that land of thine which was destroyed with thee and which nobody cared for dwelling in, shall now be so full of people that there shall be no room for the inhabitants." Here is blessing poured out till there be not room enough to receive it, Mal 3:10. Not that they shall be crowded by their enemies, or straitened for room, as Abraham and Lot were, because of the Canaanite in the land. "No, those that swallow thee up, and took possession of thy land when thy possession of it was discontinued, shall be far away. Thy people shall be numerous, and there shall be no stranger, no enemy, among them." Thus the kingdom of God among men, which had been impoverished and almost depopulated, partly by the corruptions of the Jewish church and partly by the abominations of the Gentile world, was again peopled and enriched by the setting up of the Christian church, and by its graces and glories. 4. That the new converts shall strangely increase and multiply. Jerusalem, after she has lost abundance of her children by the sword, famine, and captivity, shall have a new family growing up instead of them, children which she shall have after she has lost the other (Isa 49:20), as Seth, who was appointed another seed instead of Abel, and Job's children, which God blessed him with instead of those that were killed in the ruins of the house. God will repair his church's losses and secure to himself a seed to serve him in it. It is promised to the Jews, after their return, that Jerusalem shall be full of boys and girls playing in the streets, Zac 8:5. The church, after it has lost the Jews, who will be cut off by their own infidelity, shall have abundance of children still, more than she had when the Jews belonged to her. See Gal 4:27. They shall be so numerous that, (1.) The Children shall complain for want of room; they shall say (and it is a good hearing), "Our numbers increase so fast that the place is too strait for us;" as the sons of the prophets complained, Kg2 6:1. But, strait as the place is, still more shall desire to be admitted, and the church shall gladly admit them, and the inconvenient straitness of the place shall be no hindrance to either; for it will be found, whatever we think, that even when the poor and the maimed, the halt and the blind, are brought in, yet still there is room, room enough for those that are in and room for more, Luk 14:21, Luk 14:22. (2.) The mother shall stand amazed at the increase of her family, Isa 49:21. She shall say, Who has begotten me these? and, Who has brought up these? They come to her with all the duty, affection, and submission of children; and yet she never bore any pain for them, nor took any pains with them, but has them ready reared to her hand. This gives her a pleasing surprise, and she cannot but be astonished at it, considering what her condition had been very lately and very long. The Jewish nation had left her children; they were cut off. She had been desolate, without ark, and altar, and temple-service, those tokens of God's espousals to them; nay, she had been a captive, and continually removing to and fro, in an unsettled condition, and not likely to bring up children either for God or herself. She was left alone in obscurity (this is Zion whom no man seeks after), left in all the solitude and sorrow of a widowed state. How then came she to be thus replenished? See here, [1.] That the church is not perpetually visible, but there are times when it is desolate, and left alone, and made few in number. [2.] That yet on the other hand its desolations shall not be perpetual, nor will it be found too hard for God to repair them, and out of stones to raise up children unto Abraham. [3.] That sometimes this is done in a very surprising way, as when a nation is born at once, Isa 66:8. 5. That this shall be done with the help of the Gentiles, Isa 49:22. The Jews were cast off, among whom it was expected that the church should be built up; but God will sow it to himself in the earth, and will thence reap a plentiful crop, Hos 2:23. Observe, (1.) How the Gentiles shall be called in. God will lift up his hand to them, to invite or beckon them, having all the day stretched it out in vain to the Jews, ch. 65:2. Or it denotes the exerting of an almighty power, that of his Spirit and grace, to compel them to come in, to make them willing. And he will set up his standard to them, the preaching of the everlasting gospel, to which they shall gather, and under which they shall enlist themselves. (2.) How they shall come: They shall bring thy sons in their arms. They shall assist the sons of Zion, which are found among them, in their return to their own country, and shall forward them with as much tenderness as ever any parent carried a child that was weak and helpless. God can raise up friends for returning Israelites even among Gentiles. The earth helped the woman, Rev 12:16. Or, "When they come themselves, they shall bring their children, and make them thy children;" compare Isa 60:4. "Dost thou ask, Who has begotten and brought up these? Know that they were begotten and brought up among the Gentiles, but they are now brought into thy family." Let all that are concerned about young converts, and young beginners in religion, learn hence to deal very tenderly and carefully with them, as Christ does with the lambs which he gathers with his arms and carries in his bosom. II. That the church shall have a great and prevailing interest in the nations, Isa 49:22, Isa 49:23. 1. Some of the princes of the nations shall become patrons and protectors to the church: King shall be thy nursing fathers, to carry thy sons in their arms (as Moses, Num 11:12); and, because women are the most proper nurses, their queens shall be thy nursing mothers. This promise was in part fulfilled to the Jews, after their return out of captivity. Several of the kings of Persia were very tender of their interests, countenanced and encouraged them, as Cyrus, Darius, and Artaxerxes; Esther the queen was a nursing mother to the Jews that remained in their captivity, putting her life in her hand to snatch the child out of the flames. The Christian church, after a long captivity, was happy in some such kings and queens as Constantine and his mother Helena, and afterwards Theodosius, and others, who nursed the church with all possible care and tenderness. Whenever the sceptre of government is put into the hands of religious princes, then this promise is fulfilled. The church in this world is in an infant state, and it is in the power of princes and magistrates to do it a great deal of service; it is happy when they do so, when their power is a praise to those that do well. 2. Others of them, who stand it out against the church's interests, will be forced to yield and to repent of their opposition: They shall bow down to thee and lick the dust. The promise to the church of Philadelphia seems to be borrowed from this (Rev 3:9): I will make those of the synagogue of Satan to come and worship before thy feet. Or it may be meant of the willing subjection which kings and kingdoms shall pay to Christ the church's King, as he manifests himself in the church (Psa 72:11): All kings shall fall down before him. And by all this it shall be made to appear, (1.) That God is the Lord, the sovereign Lord of all, against whom there is no standing out nor rising up. (2.) That those who wait for him, in a dependence upon his promise and a resignation to his will, shall not be made ashamed of their hope; for the vision of peace is for an appointed time, and at the end it shall speak and shall not lie.”

“Lift up thine eyes round about, and behold,.... Look east, west, north, and south, and behold the flocking converts from all parts; see on Isa 49:12. The words are spoken to the church, and for her comfort; and so the Targum, "lift up thine eyes round about, O Jerusalem, and see all the children of the people of thy captivity:'' all these gather themselves together, and come to thee; though of different nations, and come from different quarters, yet coalesce together, make one body, and join themselves with the church, in which they centre, and are incorporated: as I live, saith the Lord; this is the form of an oath, sometimes used by the Lord, to denote the importance and certainty of a thing, and to assure his people of it: thou shalt surely clothe thee with them all as with an ornament; as children's children are the crown of old men, Pro 17:6, so young converts are the crown, glory, and ornament of the church; even such who are beautified with the graces of the Spirit, and whose conversations are as become the Gospel of Christ: and bind them on thee as a bride doeth; her clothes, the attire of her head, and her jewels. So in the latter day, when the Jews are converted, and the fulness of the Gentiles brought in, the marriage of the Lamb will be come, and the church made ready, as a bride, for her husband, and be very beautiful and comely in his sight, as well as very comfortable and glorious in herself; and which will be matter of joy to all the saints, Rev 19:7. The Targum is, "all these shall be unto thee as a garment of glory, and their works in the midst of thee as the ornament of a bride.''”

“As Zion is often compared to a bride (Isa 54:5), so the accession of converts is like bridal ornaments ("jewels," Isa 62:3; Mal 3:17). Her literal children are, however, more immediately meant, as the context refers to their restoration; and only secondarily to her spiritual children by conversion to Christ. Israel shall be the means of the final complete conversion of the nations (Mic 5:7; Rom 11:12, Rom 11:15). as a bride--namely, binds on her ornaments.”
