Isaiah 44:3 - Exposition

I will pour water upon him that is thirsty . "Water" is, in Isaiah, the common metaphor for Divine grace. Sometimes, as in this place (and Isaiah 35:6 ; Isaiah 43:20 ; Isaiah 55:1 ), the simple maim , "water" or "waters," is the word used. At other times we have instead, or in addition, "rain" ( Isaiah 5:6 ; Isaiah 30:23 ; Isaiah 55:10 ), or "dew" ( Isaiah 26:19 ), or "rivers" ( Isaiah 30:25 ; Isaiah 32:2 ; Isaiah 33:21 ; Isaiah 41:18 ; Isaiah 43:19 , etc.), or "streams" ( Isaiah 30:25 ; Isaiah 35:6 ), or "floods" (as in this place). At his coming on earth, our blessed Lord took up the comparison, and has made it familiar to all men throughout the whole Christian world (see John 3:5 ; John 4:10 , John 4:11 , John 4:13-15 ; John 7:37-39 ). We may note here that the "water" is only poured on him who is athirst for it. Thy seed … thine offspring . Not "Israel after the flesh" only, but also Israel after the Spirit—the true "Israel of God" ( Galatians 6:16 ).
