I will greatly rejoice in the LORD, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels.
I will greatly rejoice in the Lord - Zion (Isaiah 61:3) gives thanks for God's returning favour (cf. Luke 1:46-47; Habakkuk 3:18).
Garments of salvation ... robe of righteousness - inseparably connected together. The ( mª`iyl (H4598)) "robe" is a loose mantle thrown over the other parts of the dress (Psalms 132:9; Psalms 132:16; Psalms 149:4; Revelation 21:2; Revelation 19:8).
As a bridegroom decketh himself with ornaments - rather, maketh himself a priestly head-dress ( paa'eer (H6286), Isaiah 61:3); i:e., a magnificent head-dress, such as was worn by the high priest-namely, a mitre and a plate, or crown of gold worn in front of it, (Aquila, etc.) Appropriate to the "kingdom of priests," dedicated to the offering of spiritual sacrifices to God continually (Exodus 19:6; Revelation 5:10; Revelation 20:6).
Jewels - rather, ornaments in general. The bride's trousseau ( keeleyhaa (H3627)).
