Isaiah 49:5 Douay-Rheims

And now saith the Lord, that formed me from the womb to be his servant, that I may bring back Jacob unto him, and Israel will not be gathered together: and I am glorified in the eyes of the Lord, and my God is made my strength.

“"Who formed me from the womb to be his servant." This is clearly said with reference to Zerubbabel and the people but was accomplished in Christ. And indeed, since Christ will descend from them, it is with good reason that what concerns him is represented in them as in a sign.”

“That formed me, etc. God formed me, that I should rebuke Israel, till they returned to Him. לא Unto him. The original reading is לו unto him, as the Masorah recommends; comp. Ps. 100:5; there are some more instances of the same kind. According to the Gaon, the meaning of לא יאסף is: Will not die; he generally explains both the Keri and the Ketib; but what I said, is nevertheless right, and לא of the text is the same as לו, as the Grammarian R. Jehudah explained.”

“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.”

“And now, saith the Lord,.... Jehovah the Father, in confirmation of the call, office, and work of Christ, which he hath declared, Isa 49:1, that formed me from the womb to be his servant; who preordained him to this service before the world began, and prepared him for it from the womb of his mother Mary, by filling him with grace and wisdom and with the Spirit without measure; anointing him with the oil of gladness above his fellows, and so fitting him as man and Mediator for the preaching of the Gospel, and every other service he called him: to bring Jacob again, to him; the lost sheep of the house of Israel, God's elect among the Jews, which were as straying sheep; or all his chosen people, whether Jews or Gentiles, which were scattered abroad, and were afar off from God, whom Christ was to bring back again, and bring nigh unto God, and did: though Israel be not gathered: in general, only a remnant, according to the election of grace, the greater part refusing to be gathered ministerially by him; and the rulers not suffering the common people to attend on his ministry. Mat 23:37. It may be observed that there is a marginal reading of the Hebrew, different from the written text; instead of "not" it is "to him"; and may be rendered thus, "and Israel shall be gathered unto him"; and then the sense entirely agrees with the preceding clause, with which the words are connected, and not with the following, as the accent "athnach" shows, thus; the Lord appointed and formed me to be his servant to bring back Jacob, and that Israel might be gathered to him; as all the Israel of God, all the elect of God were by the sufferings and death of Christ; see Eph 1:10. The marginal reading, and the writing, may be both retained, as in some other places, thus, "and shall not Israel be gathered to him?" since he has formed me to bring back Jacob to him? verily he shall. The marginal reading is followed by the Targum, and the passage paraphrased thus, "to return the house of Jacob to his service, and Israel shall be brought nigh, to his fear.'' And so it is by Jarchi, Aben Ezra, and Kimchi, and by the Septuagint, Syriac, and Arabic versions, and by Aquila: "yet shall I be glorious" in the eyes of the Lord; or "I shall be glorious", &c.; as he was at his baptism and transfiguration on the mount; by the wonderful things done in heaven and on earth at the time of his death, at his resurrection from the dead, his ascension to heaven, and exaltation at the right hand of God, far above all principalities and powers, angels, authorities, and powers, being subject to him; and by the ministration of the Gospel in the Gentile world, and particularly when he shall reign gloriously in the latter day, and in the New Jerusalem church state: and my God shall be my strength; to keep up his spirits under all discouragements; to protect him from his enemies; to support him in his work as man; to carry him through it, and enable him completely to perform it, as he promised he would, and as he did, Isa 49:8.”

“Will not. Hebrew, Septuagint, &c., “to be gathered.” (Haydock) — The original text, independent of the Masorets, may have the sense of the Vulgate. Yet there are other proofs of the synagogue’s rejection. (Calmet) — Protestants, “though Israel be not gathered, yet,” &c. Marginal note, or “that Israel may be gathered, and I may,” &c. (Haydock)”

“The negation was read by 8t. Jerome i is found in the margin of many MSS., which R. thinks is the correct reading, or at least the true meaning. Christ, according to the flesh, is servant of His Father, since He has taken on Him the form of a servant, in order to gather together the dispersed chil- dren of God.”

“The reason why He was confident that His work would be accepted and rewarded, namely, because He is "glorious in the eyes of Jehovah," &c. to bring Jacob again to him-- (Mat 15:24; Act 3:26). Though Israel be not gathered--metaphor from a scattered flock which the shepherd gathers together again; or a hen and her chickens (Mat 23:37). Instead of the text "not," the Keri has the similar Hebrew word, "to Him," which the parallelism favors: "And that Israel may be gathered to Him." yet--rather, parenthetically. "For I am glorious, &c., and My God is My strength." Then (Isa 49:6) resuming the words from the beginning of Isa 49:5, "He saith" (I repeat), &c. HORSLEY explains, "Notwithstanding the incredulity of the Jews, Messiah shall be glorified in the conversion of the Gentiles," reading as English Version: but if the Keri be read, "Israel shall at one time or other be gathered, notwithstanding their incredulity during Messiah's sojourn on earth."”

“The expression "and now" (ועתּה), which follows, evidently indicates a fresh turn in the official life of the person speaking here. At the same time, it is evident that it is the failure of his labours within his own people, which has forced out the lamentation in Isa 49:4. For his reason for addressing his summons in Isa 49:1 to the world of nations, is that Jehovah has not guaranteed to him, the undaunted one, success to his labours among his own people, but has assigned him a mission extending far beyond and reaching to all mankind. "And now, saith Jehovah, that formed me from the womb to be His servant, to bring back Jacob to Him, and that Israel may be gathered together to Him; and I am honoured in the eyes of Jehovah, and my God has become my strength. He saith, It is only a small thing that thou becomest my servant, to set up the tribes of Jacob, and to bring back the preserved of Israel. I have set thee for the light of the Gentiles, to become my salvation to the end of the earth." Both shōbhēbh and hâshı̄bh unite within themselves the meanings reducere (Jer 50:19) and restituere. On לא = לו generally, see at Isa 9:2; Isa 63:9. Jerome is wrong in his rendering, et Israel qui non congregabitur (what could a prophecy of the rejection of the Jews do here?); so also is Hitzig's rendering, "since Israel is not swept away;" and Hofmann's, "Israel, which is not swept away." In the present instance, where the restoration of Israel is the event referred to, אצף must signify "the gathering together of Israel," as in Isa 11:12. לו (parallel אליו) points to Jehovah as the author of the gathering, and as the object of it also. The transition from the infinitive of design to the finite verb of desire, is the same as in Isa 13:9; Isa 14:25. The attributive clause, added to the name Jehovah, expresses the lofty mission of the servant of God with regard to Israel. The parenthesis, "I have honour in the eyes of Jehovah, and my God has become my strength, i.e., has become mighty in me, the apparently weak one," looks beyond to the still loftier mission, by which the former lofty one is far surpassed. On account of this parenthetically inserted praise of Jehovah, the אמר is resumed in ויּאמר. Instead of נקל היותך (compare Kg1 16:31), i.e., it is a small thing that thou shouldst be, we have it here, as in Eze 8:17, with a comparative min, which must not, however, be logically pressed: "It is smaller than that," i.e., it is too small a thing that thou shouldst be. The netsı̄rē (Keri, netsūrē) of Israel are those who have been preserved in exile (Eze 6:12); in other cases, we find שׁאר, שׁארית, or פּלטה. Not only is the restoration of the remnant of Israel the work of the servant of Jehovah; but Jehovah has appointed him for something higher than this. He has given or set him for the light of the heathen ("a light to lighten the Gentiles," Luk 2:32), to become His salvation to the end of the earth (lxx: τοῦ εἶναι σε εἰς σωτηρίαν ἕως ἐσχάτου τῆς γῆς). Those who regard Israel as a nation as speaking here (e.g., Hitzig, Ewald, Umbreit, etc.) go right away from this, which is the most natural sense of the words, and explain them as meaning, "that my salvation may be, reach, or penetrate to the end of the earth." But inasmuch as the servant of Jehovah is the light of the world, he is through that very fact the salvation of the world; and he is both of these through Jehovah, whose counsels of ישׁוּעה are brought by him into historical realization and visible manifestation.”
