The salvation promised in the foregoing chapter being compared to that of Israel, in the day when they came out of the land of Egypt; and Moses and Israel having then sung a song of praise, to the glory of God; the prophet here puts a eucharistic hymn into the mouths of the Lord's redeemed under the Christian dispensation, when the root of Jesse should stand for an ensign of the people, and become the desire and joy of all nations.
(1,) Every particular believer shall sing a song of praise for his own interest in that salvation, Isaiah 12:1-3. Thou shalt say, Lord, I will praise thee.
(2,) Many in concert shall join in praising God for the common benefit arising from it, Isaiah 12:4-6. Ye shall say, Praise the Lord.
