Jesaja 12:6

As Israel, when redeemed from Egypt beyond the Red Sea, sang songs of praise, so also will the Israel of the second redemption, when brought, in a no less miraculous manner, across the Red Sea and the Euphrates. "And in that day thou wilt say, I thank Thee, O Jehovah, that Thou wast angry with me: Thine anger is turned away, and Thou hast comforted me. Behold, the God of my salvation; I trust, and am not afraid: for Jah Jehovah is my pride and song, and He became my salvation." The words are addressed to the people of the future in the people of the prophet's own time. They give thanks for the wrath experienced, inasmuch as it was followed by all the richer consolation. The formation of the sentence after כּי is paratactic; the principal tone falls upon 1b, where yâshōb is written poetically for vayyâshob (cf., Deu 32:8, Deu 32:18; Psa 18:12; Hos 6:1). We hear the notes of Psa 90:13; Psa 27:1, resounding here; whilst Isa 12:2 is the echo of Exo 15:2 (on which Psa 118:14 is also founded). עזי (to be read ‛ozzi, and therefore also written עזי) is another form of עזּי, and is used here to signify the proud self-consciousness associated with the possession of power: pride, and the expression of it, viz., boasting. Zimrath is equivalent in sense, and probably also in form, to zimrâti, just as in Syriac zemori (my song) is regularly pronounced zemōr, with the i of the suffix dropped (see Hupfeld on Psa 16:6). It is also possible, however, that it may be only an expansion of the primary form zimrath = zimrâh, and therefore that zimrath is only synonymous with zimrâti, as chēphetz in Sa2 23:5 is with chephtzi. One thing peculiar to this echo of Exo 15:2 is the doubling of the Jah in Jâh Jehōvâh, which answers to the surpassing of the type by the antitype.

The salvation promised in the foregoing chapter was compared to that of Israel "in the day that he came up out of the land of Egypt;" so that chapter ends. Now as Moses and the children of Israel then sang a song of praise to the glory of God (Exo 15:1) so shall the people of God do in that day when the root of Jesse shall stand for an ensign of the people and shall be the desire and joy of all nations. In that day, I. Every particular believer shall sing a song of praise for his own interest in that salvation (Isa 12:1, Isa 12:3). "Thou shalt say, Lord, I will praise thee." Thanksgiving-work shall be closet-work. II. Many in concert shall join in praising God for the common benefit arising from this salvation (Isa 12:4-6): "You shall say, Praise you the Lord." Thanksgiving-work shall be congregation-work; and the praises of God shall be publicly sung in the congregations of the upright.
