Isaiah 12
PATThis chapter is a hymn of praise, proper to be used in that triumphant state of the church, described in the foregoing chapter. Of the same use are the hymns recorded xxv. xxvi. and Rev. xxv. 3. Many of the Psalms relate to the same glorious time, particularly Psal. xcii. xcvi. xcvii. cxlix.
Isaiah 12:3
THEREFORE with joy shall ye draw water out of the wells of salvation. From God’s mercy and bounty, who is the fountain of life, and of all blessings, both spiritual and temporal, (Psal. xxxvi. 9. Jer. ii. 13.) The Jews did use to repeat this verse, when, with a great deal of joy and ceremony, they drew water out of the river of Shiloah upon the last day of the feast of tabernacles; to which custom our Saviour is supposed to allude, John vii. 37.
