Some make this the song of joy and praise to be sung by the prophet in the name of Jerusalem, congratulating her on the happy change of her circumstances in the accomplishment of the foregoing promises; others make it to be spoken by Christ in the name of the New Testament church triumphing in gospel grace. We may take in both, the former as a type of the latter. We are here taught to rejoice with holy joy, to God's honour, 1. In the beginning of this good work, the clothing of the church with righteousness and salvation, Isa 61:10. Upon this account I will greatly rejoice in the Lord. Those that rejoice in God have cause to rejoice greatly, and we need not fear running into an extreme in the greatness of our joy when we make God the gladness of our joy. The first gospel song begins like this, My soul doth magnify the Lord, and my spirit hath rejoiced in God my Saviour, Luk 1:46, Luk 1:47. There is just matter for this joy, and all the reason in the world why it should terminate in God; for salvation and righteousness are wrought out and brought in, and the church is clothed with them. The salvation God wrought for the Jews, and that righteousness of his in which he appeared for them, and that reformation which appeared among them, made them look as glorious in the eyes of all wise men as if they had been clothed in robes of state or nuptial garments. Christ has clothed his church with an eternal salvation (and that is truly great) by clothing it with the righteousness both of justification and sanctification. The clean linen is the righteousness of saints, Rev 19:8. Observe how these tow are put together; those, and those only, shall be clothed with the garments of salvation hereafter that are covered with the robe of righteousness now: and those garments are rich and splendid clothing, like the priestly garments (for so the word signifies) with which the bridegroom decks himself. The brightness of the sun itself is compared to them. Psa 19:5, He is as a bridegroom coming out of his chamber, completely dressed. Such is the beauty of God's grace in those that are clothed with the robe of righteousness, that by the righteousness of Christ are recommended to God's favour and by the sanctification of the Spirit have God's image renewed upon them; they are decked as a bride to be espoused to God, and taken into covenant with him; they are decked as a priest to be employed for God, and taken into communion with him. 2. In the progress and continuance of this good work, Isa 61:11. It is not like a day of triumph, which is glorious for the present, but is soon over. No; the righteousness and salvation with which the church is clothed are durable clothing; so they are said to be, Isa 23:18. The church, when she is pleasing herself with the righteousness and salvation that Jesus Christ has clothed her with, rejoices to think that these inestimable blessings shall both spring for future ages and spread to distant regions. (1.) They shall spring forth for ages to come, as the fruits of the earth which are produced very year, from generation to generation. As the earth, even that which lies common, brings forth her bud, the tender grass at the return of the year, and as the garden enclosed causes the things that are sown in it to spring forth in their season, so duly, so constantly, so powerfully, and with such advantage to mankind will the Lord God cause righteousness and praise to spring forth, by virtue of the covenant of grace, as, in the former case, by virtue of the covenant of providence. See what the promised blessings are - righteousness and praise (for those that are clothed with righteousness show forth the praises of him that clothed them); these shall spring forth under the influence of the dew of divine grace. Though it may sometimes be winter with the church, when those blessings seem to wither and do not appear, yet the root of them is fixed, a spring-time will come, when through the reviving beams of the approaching Sun of righteousness they shall flourish again. (2.) They shall spread far, and spring forth before all the nations; the great salvation shall be published and proclaimed to all the world and the ends of the earth shall see it.

I will greatly rejoice in the Lord - These may be the words of the Jews now converted, and brought into the Church of Christ, and with the Gentiles made fellow heirs of the blessings of the new covenant.

As a bridegroom decketh himself with ornaments "As the bridegroom decketh himself with a priestly crown" - An allusion to the magnificent dress of the high priest, when performing his functions; and particularly to the mitre, and crown or plate of gold on the front of it, Exo 29:6. The bonnet or mitre of the priests also was made, as Moses expresses it, "for glory and for beauty, "Exo 28:40. It is difficult to give its full force to the prophet's metaphor in another language. The version of Aquila and Symmachus comes nearest to it: ὡς νυμφιον ἱερατευομενον στεφανῳ· "as a bridegroom decked with a priestly crown." - L.

I will greatly rejoice in the Lord,.... These are not the words of the prophet spoken in his own person, rejoicing in the goodness of the Lord to his people and countrymen; nor of Christ; but of the church, especially the Jewish church, expressing her joy for benefits received, as declared in the preceding verses. The Targum is,

"Jerusalem said, rejoicing I will rejoice in the Word of the Lord;''

not in his word of promise, but in his essential Word, his Son the Messiah; in his person, offices, fulness, righteousness, and salvation:

my soul shall be joyful in my God; in Christ, in that he is God, and so able to save to the uttermost, and keep from a final and total falling, and to preserve safe to his kingdom and glory: hence his person is excellent; his blood precious; his righteousness valuable; and his sacrifice efficacious; and all matter of joy to the believer: and who also rejoices in that he is his God, "my God"; God in our nature; Immanuel, God with us; the God-man and Mediator, through whom there is access to God and acceptance with him; and who stands in near relation to his people, and has all fullness to supply their wants, and makes all he has theirs; so that, they have great reason to rejoice in him indeed. The Targum is,

"my soul shall rejoice in the salvation of my God;''

the nature of this joy may be collected from the text itself: it is not a carnal one, or the joy of a carnal man in carnal things, it is spiritual; nor a pharisaical joy, a rejoicing in a man's self, in his own works of righteousness, for this "is in the Lord"; nor is it a hypocritical one, or only externally, for it is the soul that rejoices; and it is the joy of faith, or in the Lord, as "my God"; and a very great one it is, joy unspeakable, and full of glory; and is what continues, as the matter and ground of it always does, as follows: "for he hath clothed me with the garments of salvation"; with salvation as garments; the salvation of Christ, which, like garments, is without men, being wrought out by Christ; and is brought near, and applied by the spirit of Christ; and is all around, and encompasses the saints as such, and like them beautifies and adorns them, and keeps them warm and comfortable, when they have the joys of it; and which secures them from the storms of divine wrath and vengeance; and the plural number being used may denote the fulness and completeness of this salvation, from all sin, from wrath, hell, and damnation, and from every enemy: and this is matter of joy to the believer interested in it, and clothed with it; since it is a salvation so great; a garment so fitting and suitable, and had at free cost; and in which the glory of all the divine perfections is so conspicuous, as well as it being so full, complete, and perfect, and an everlasting one:

he hath covered me with the robe of righteousness: not with her own, that is a rag, and not a robe, and a filthy one too, Isa 64:6 and no covering, and is indeed no righteousness, properly speaking; but the righteousness of Christ, the best robe, the wedding garment, and change of raiment, which, like a robe, is upon believers, but not in them; it in Christ, and imputed to them; it covers their persons and their nakedness, and all their sins, so as not to be seen with the eye of avenging justice: to clothe and cover with it is God's act of imputation, and Christ's application of it by his Spirit, Zac 3:4, which, perceived by the believer, causes great joy; it being all of a piece, like Christ's seamless robe, and so pure and spotless, so perfect and complete, and so rich and glorious:

as a bridegroom decketh himself with ornaments; or, "adorns" himself

in a princely or priestly manner (d); for the word used signifies both. The sense is, as a bridegroom puts on the best clothes he has on his wedding day, and makes the appearance of a prince in his richest robes, or as the high priest when he had on all his sacerdotal garments; so the Targum,

"as a bridegroom that flourishes in his bridechamber, and as the high priest who is adorned with his garments:''

and as a bride adorneth herself with her jewels; or "implements" (e); and makes herself as fine as she can, to recommend herself to her spouse and her friends: thus richly and magnificently arrayed is the church of Christ, and every believer, being clothed with his righteousness; he and they are in the same relation; he is the bridegroom, they the bride; and they are clothed alike with the garment down to the foot; and are righteous as he is righteous; and are herewith as a bride adorned and made ready for her husband; and the joy at such a solemnity fitly expresses the mutual joy of Christ and his church; see Rev 19:7 so Christ's righteousness is compared to a wedding garment, Mat 22:12.

(d) "sacerdotali more ornabit", Tigurine version; "qui sacerdotem refert ornatu", Piscator. (e) "vasis suis", Vatablus, Montanus; "instrumentis"; Junius & Tremellius, De Dieu.

Zion (Isa 61:3) gives thanks for God's returning favor (compare Luk 1:46-47; Hab 3:18).

salvation . . . righteousness--inseparably connected together. The "robe" is a loose mantle thrown over the other parts of the dress (Psa 132:9, Psa 132:16; Psa 149:4; Rev 21:2; Rev 19:8).

decketh himself with ornaments--rather "maketh himself a priestly headdress," that is, a magnificent headdress, such as was worn by the high priest, namely, a miter and a plate, or crown of gold worn in front of it [AQUILA, &c.]; appropriate to the "kingdom of priests," dedicated to the offering of spiritual sacrifices to God continually (Exo 19:6; Rev 5:10; Rev 20:6).

jewels--rather, "ornaments" in general [BARNES].
