'Living Water' in the Bible

Jesus answered her, "If you knew the gift of God, and who it is that is saying to you, 'Give me a drink,' you would have asked him, and he would have given you living water."

The woman said to him, "Sir, you have nothing to draw with, and the well is deep. Where do you get that living water?

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

For the Lamb in the center of the throne will be their shepherd, and he will guide them to springs of living water; and God will wipe away every tear from their eyes."
