Isaiah 66:20 Douay-Rheims

And they shall bring all your brethren out of all nations for a gift to the Lord, upon horses, and in chariots, and in litters, and on mules, and in coaches, to my holy mountain Jerusalem, saith the Lord, as if the children of Israel should bring an offering in a clean vessel into the house of the Lord.

“Thus says the Lord. Here he determines the manner of the execution of the sentence already given: and first specifically as regards the Jews; second universally as regards all: but I, their works and thoughts. The first is divided into two: in the first he excludes false confidence; second he sets forth and determines the sentence given, as to the manner of its execution: Hear the word of the Lord. Concerning the first there are two parts. First he excludes false confidence in the holiness of the temple, showing that the temple is not the place of God: both from the greatness of God, who fills all things — whose seat heaven is called, because it shares abundantly in his goodness, just as a seat holds the greater part of the one sitting; while earth is his footstool, because the earth shares least in his goodness, just as the outermost part reaches only to the footstool — or by heaven the saints are meant, and by earth the earthly-minded. 3 Kings 8: if heaven and the heaven of heavens do not contain you. Jeremiah 23: I fill heaven and earth. Acts 17: not in the hand-made things of the temple. Then from rest: because each thing rests in the place that is its own place; but God does not rest in anything, rather all things rest in him, as made by him. And what is his place? Above, ch. 40: lift up on high. And he gives a useful remedy: but to whom — the poor one, that is, the humble man who considers himself small as to the present; the contrite, as to past sins; the trembling, as to his resolve concerning what is to be done in the future. Ecclesiasticus 15: his eyes are upon those who fear him. Second, he excludes the confidence they had conceived from the rite of sacrifices: and first he sets down their reprobation: he who sacrifices an ox — as if he were to say: their sacrifices are so abominable, as if they were doing something against the law, because they were offering the same things to idols. He who blesses — that is, praises and venerates. Above, ch. 1: do not offer sacrifice any more. Second, he shows the reason for the reprobation, first setting down their fault: they have chosen all these things — namely, the sacrifices — walking in their own ways, evil ones. Proverbs 2: they rejoice when they have done evil, and exult in the worst of things. Second, he threatens punishment: hence, and I — Proverbs 3: he himself will mock the mockers. Job 3: the fear that I feared has come upon me, and what I dreaded has happened to me. Third, he charges the sinners with hardness of heart: because I called — Proverbs 1: I called, and you refused. Hear the word of the Lord. Here he carries out the manner of executing the sentence already given: and first as to the rewards of the good; second as to the punishments of the wicked: and it shall be known. The first is in two parts. First he rouses attention: you who tremble, out of reverence for his words. Ecclesiasticus 2: you who fear the Lord, believe in him. Second, he pursues the promise: and first as to vengeance upon the mockers, setting down their mockery: your brothers have said. Let him be glorified — as if to say: let the glory of the Lord appear, which you expect — as if to say: it will never appear. Above, ch. 5: he will come quickly and swiftly, he will not fail nor grow weary in it. And foretelling their confusion: but they shall be confounded, in this way: a voice of the people, fearing; a voice of the Lord, as to the tumult of enemies. Zephaniah 1: the voice of the day of the Lord is bitter. Second, he carries out the promise as to the abundance of good things: and first as to the reuniting of the people, setting down the promise: before she was in labor — that is, suddenly, and at once, the children of Jerusalem shall be gathered to her, just as if a woman should suddenly bring forth a son, with no labor going before. Above, ch. 37: the children have come as far as the birth. Mystically it is expounded of the childbearing of the Blessed Virgin, and of the childbearing of the Church in the conversion of the faithful, and of the bringing-forth of the eternal generation. And he introduces a question of wonder: who has ever heard such things? Above, ch. 49: who has begotten for me? And he sets down the answer in the person of the Lord: shall not I myself bring forth? — gathering the Jews, or converting the faithful, or the Son from eternity. Similarly, Psalm 93: he who planted the ear, shall he not hear? Or he who formed the eye, does he not consider? And these arguments hold, if that which is of perfection in creatures is attributed to him, with everything that belongs to imperfection removed. Second, he promises immense consolation to those gathered. And first he invites others to rejoice with them: rejoice with Jerusalem — in her, as in the object of joy — setting down the condition of those who rejoice together, as to affection: you who love. Canticle of Canticles 5: eat, O friends, and drink, and be inebriated, dearest ones. As to the sign of affection: you who mourn. Matthew 5: blessed are they who mourn, for they shall be comforted. And the fruit of that shared rejoicing, as to the sharing of gladness, or of peace: that you may suck — Canticle of Canticles 1: your breasts are better than wine. As to the sharing of glory: that you may milk it out, as those who milk out milk. Job 22: then you shall abound in delights over the Almighty. Second, he promises a copious bestowal of peace: for thus says the Lord: I will turn — so that it may be called an overflow, like a river which, though it comes down with great force, does not overflow. And of glory, and as it were a torrent. Above, ch. 48: it would have been made like a river. Third, he promises the full reception of consolation. First as to the administering of the nations: which you shall suck — unto the glory of the nations, because the kings of the nations themselves shall comfort you, and shall sustain you. Hence there follows, at the breasts. Mystically he speaks of the apostles, who rejoiced in the glory of the nations swiftly converted, and carried them, as it were, to the breasts by gentle admonitions. Above, ch. 60: you shall suck milk. Second, as to the divine protection: as if to someone, a mother. Hebrews 12: you have forgotten the consolation. Third, as to the enjoyment of good things: you shall see — the good things given you by God; your bones — you who in adversity were like dry bones. Ezekiel 37: dry bones, hear the word of the Lord. Or, you shall see the divine essence. Ecclesiastes 11: light is sweet, and it is delightful for the eyes to see the sun. Bones, unto the resurrection. And it shall be known. Here he promises punishments to the wicked: and first he threatens punishment, setting down the indignation of the judge: the hand, afflicting the wicked among his servants. Or, the hand of consolation, among his servants, through its effect. Above, ch. 27: there is no indignation in me. He also sets down the greatness of the punishment: for behold, the Lord — in fire, by which the city was to be burned, or by which the world was to be purged. Chariots — the army of the Chaldeans, in which God comes, as it were; or the Angels who will come with him to judgment. Psalm 96: fire shall go before him. Amos 9: they shall perish by the sword of God. He also sets down the multitude of those punished: they shall be multiplied. Above, ch. 34: for the victim of the Lord is in Bosra, and a great slaughter in the land of Edom. Second, he reproaches their guilt: who were sanctifying themselves, thinking to cleanse themselves from uncleanness by waters, or even by the sacrifices of idols, in the gardens, in which they worshipped idols, or gave themselves over to pleasure, after one, coupling with women after the manner of beasts. Or, behind the door — literally, the mouse, the dormouse, against the law, Leviticus 11. Above, ch. 65: they eat swine's flesh, and unclean broth. But I. Here he pursues the manner of the discernment as regards all in common: and first he proclaims the universal judgment: their works and thoughts — judging, as it were, for both together; I come, on the day of judgment. Or, the various kingdoms of your enemies, and destroying the wicked among you. They shall come, to Jerusalem after your return, or to judgment, or to the faith. Joel 3: behold, I will raise them up out of the place in which you sold them. Second, he sets down the summons: and I will set among them — that is, among the Jews who shall be with Zerubbabel and the other leaders — a sign, the edict of Cyrus, to the nations, to which the Jews had been scattered; to Lydia, those who hold the arrow, because they are good archers; my glory, which shall appear in your deliverance. Above, ch. 11: he shall lift up a sign among the nations. Or, he sets the sign of the cross among the apostles, that all may be turned to God, as it were preparing them for judgment. Third, he sets down the preparation of those who are to be judged: and first as to the good; second as to the wicked: and they shall go forth, and shall see. The first is in two parts. First, as to the Jews, setting down their honorable return: they shall bring them on horses — by which are signified the aids which those returning had from the Gentiles. Baruch 5: the Lord shall bring these to you. Or there are signified the various conditions of those who are converted to the faith, as the Gloss expounds. Second, the exaltation of their return, first as to dignity: and I will take — which was fulfilled literally in the Jews, and also in the apostles. Above, ch. 61: you shall be called the priests of the Lord; it shall be said of you, ministers of our God. Second, as to the preservation of their offspring: for as the new heavens, as above, ch. 65 — so shall it stand, forever. Jeremiah 31: if these laws shall fail before me, says the Lord, then the seed of Israel also shall fail. Or, the saints shall stand forever, renewed like heaven and earth. Third, as to the duration of their glory: and it shall be month — as though month shall succeed month, and feast shall succeed feast, in your prosperity. Above, ch. 29: year has been added to year, and the solemnities have run their course. Mystically, the Church after the end; spiritual rest after carnal. Second, as to the Gentiles: and all shall come — because from the various nations they came to Jerusalem to worship the Lord. Psalm 85: all the nations shall come and shall adore before you, O Lord. Or, on the day of judgment: and they shall go forth. Here he sets down the second judgment, as regards the wicked: and first the outflow of the punishment: and they shall go forth, coming to Jerusalem, and they shall see, in the ancient tombs, and in the fields, the bones of their dead fathers. Above, ch. 34: their slain shall be cast out, and from their carcasses a stench shall rise. Or, the saints shall see the damned falling into damnation. Second, he sets down the duration of the punishment: their worm — of conscience, by which even the dead shall be tormented; and fire — of hell. Judith 16: he will give fire and worms into their flesh. Third, the delight taken in these punishments, as regards those who see them: and they shall be unto satiety to all flesh — that is, to the saints. Psalm 57: the just shall rejoice when he shall see the revenge. From these punishments may he free us, who has granted both to begin and to complete. And thus ends the sentence and the literal exposition on Isaiah according to Brother Thomas Aquinas, which Brother Iacobinus of Asti, of the province of Lombardy, at that time a student in the general house of studies at Naples, transcribed into legible letters, completing the authorities. He also arranged collations at certain places upon each of the lectures, and this he did for the benefit of the friars of our order, and that copies of the said writings might be had. Therefore, praise be to him who granted both to begin and to complete. Amen.”

“And they shall bring all your brethren, for an offering unto the Lord, out of all nations,.... This is not said of the Jews, either with respect to the first times of the Gospel; not of the devout men of all nations that heard the apostles on the day of Pentecost; nor of those the Gospel met with in the Gentile world, by the ministry of the apostles, to whom Peter and James write their epistles; or, in the latter day, such who remain in the several nations after the general conversion of that people; but this is to be understood of the Gentiles, and of the bringing in the fulness of them, by means of those who shall escape the calamities of those times, the destruction of the eastern and western antichrist; some of which will become preachers of the word, and be the instruments of doing this work: here the Gentiles are called the brethren of the converted Jews, as all the Lord's people are brethren one of another, be they of what nation they will; they are all in a spiritual sense the seed and children of Abraham, who is the father of all that believe; and so all believers are brethren, Jews and Gentiles; yea, they are all the children of God, who is the one God and Father of all, in the covenant of grace, which is common to them all; and by adoption, and through regeneration, the evidence of it. Christ stands in the relation of an elder brother to them all; and the church universal, the Jerusalem above, is the mother of them all; they are mother's children, and so brethren; they are partakers of the same blessings and privileges, and heirs of the same promises, grace, and glory: now all those that are predestinated to the adoption of sons, that are the children of God scattered abroad, and whom God has promised to call by his grace, shall be brought in; not one shall be left behind; such is the will of God, which cannot be resisted; such their election of grace, which stands firm on the sovereign will of God, and, always obtains; such the suretyship of Christ, and the purchase of his blood, which make the bringing of them absolutely necessary; and the Lord knows where they are, and will send his Gospel and ministers to them, to fetch them in, let them be in ever such distant and obscure places: and these shall be brought, for an offering to the Lord; which shall be offered to him, either by the persons that bring them, the ministers of the Gospel, who are the priests of the Lord, Isa 66:21 and who offer, not slain beasts, as under the law, but living persons, men and women, converted under their ministry; whom they bring to the Lord, and to his house, as trophies of his victorious grace, to serve and glorify him. The Apostle Paul seems to allude to this passage, and to give the sense of it, Rom 15:16 or else by themselves that are brought; who shall present their souls and bodies a living, holy, and acceptable sacrifice unto God, as their reasonable service; not to atone for their sins, but in gratitude to the Lord, as being his, and not their own, Rom 12:1 the means by which they shall be brought follows: upon horses, and in chariots, and in litters, and upon mules, and upon swift beasts; which Kimchi and Aben Ezra interpret of camels, the better sort of them; but the Targum renders it, with praises; and so Jarchi understands it of the songs of those that skip and dance for joy; see Sa1 6:16, which carriages are not to be understood literally, but figuratively, expressive of the Gospel ministry, which is the vehicle of salvation, and in which souls are brought to Christ, and to his church; and various sorts being mentioned, may signify the multitudes that shall be gathered in, and the different accommodations made, according to different circumstances; some that are strong and eager, and impatient of church communion, are brought on more speedily, on horses, and swift beasts; and others more weakly, and can move but slowly, in chariots and litters; and all denote the safe and honourable way and manner in which they are conducted, as well as the welcome they may expect to have in the churches of Christ; since all manner of help is afforded to them. The horse is an emblem of the Gospel ministry, and so is the chariot, Rev 6:2 the place they will be brought unto is, to my holy mountain Jerusalem, saith the Lord; not Jerusalem literally taken, though it is highly probable it will be at this time a place of great resort of all Christians; but the church, often called by this name in this prophecy, and in this chapter; a "mountain", for height, visibility, and especially for firmness and immovableness; a "holy" one, where holy things, words, and ordinances are ministered, holy persons meet, and none else should be members of it; hither converted persons are brought, to partake of those holy things, and have communion with holy persons, by means of the ministers of the Gospel, who invite, exhort, encourage, and persuade, and use the most forcible arguments they can, but after all are but instruments, God is the cause; it is he that brings souls to Zion, Jer 3:14 the manner follows: as the children of Israel bring an offering in a clean vessel into the house of the Lord; just as the "minchah", or meat offering, was brought in a pure and clean vessel into the sanctuary of the Lord, and there presented before him; as all the vessels there were Holy Ones, Ezr 8:28 denoting who those should be that should be brought and offered; persons whose hearts were purified by faith in the blood of Christ; called with a holy calling; sanctified by the Holy Ghost; and appearing in the beauties of holiness of heart and life. The Septuagint version renders it, "with psalms"; and the Arabic version, "with a jubilee"; suggesting they should be brought with joy and gladness; see Psa 45:15. The ancient Jews (p) interpret all this of the gifts brought to the King Messiah in his days. (p) Midrash Tillim apud Yalkut in Psal. Ixxxvii. 4.”

“they--the Gentiles (Isa 66:19). bring . . . your brethren--the Jews, back to the Holy Land (Isa 49:22). It cannot mean the mere entrance of the Jews into the Christian Church; for such an entrance would be by faith, not upon "horses, litters, and mules" [HOUBIGANT]. "Offering" is metaphorical, as in Rom 15:16. horses--not much used by the Jews. The Gentiles are here represented as using their modes of conveyance to "bring" the Jews to Jerusalem. chariots--as these are not found in Oriental caravans, translate, "vehicles," namely, borne, not drawn on wheels. litters--covered sedans for the rich. upon swift beasts--dromedaries: from Hebrew root, "to dance," from their bounding motion, often accelerated by music [BOCHART]. Panniers were thrown across the dromedaries' back for poorer women [HORSLEY].”
