John Dummelow's Commentary
Isaiah 12
1. The thanksgiving that now follows is the counterpart of the hymn of praise sung after the passage of the Red Sea (Exodus 15), and is partly based upon it. Some scholars doubt its Isaianic authorship and date it after the return from exile.
3. Draw water] Under a figure it is indicated that there shall be a continual supply of divine protection and deliverance. Or, if we follow the Talmud, there may be an allusion to the ceremonial of the Feast of Tabernacles, on the last day of which water was drawn from the pool of Siloam by the priests and poured at the altar of burnt-offering (see John 7:37).
5. He hath done excellent things] from Exodus 15:1, 'triumphed gloriously,' the same word. This is known] RV 'let this be known.'
