Isaiah 41:17-18

17“When the poor and needy search for water and there is none, and their tongues are parched from thirst, then I, the Lord, will answer them. I, the God of Israel, will never abandon them.

18I will open up rivers for them on the high plateaus. I will give them fountains of water in the valleys. I will fill the desert with pools of water. Rivers fed by springs will flow across the parched ground.
