Isaiah 41:17,18

The poor and needy seek water, but there is none, their tongues fail for thirst. I, the Lord, will hear them; I, the God of Israel, will not forsake them. I will open rivers in desolate heights, and fountains in the midst of the valleys; I will make the wilderness a pool of water, and the dry land springs of water.

John 7:38

He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.
