'Living Water' in the Bible

“You are a fountain in a garden,A well of fresh and living water,And streams flowing from Lebanon.”

“For My people have committed two evils:They have abandoned (rejected) Me,The fountain of living water,And they have carved out their own cisterns,Broken cisternsThat cannot hold water.

O Lord, the hope of Israel,All who abandon You will be shamed.Those who turn away on earth will be written down,Because they have abandoned the Lord, the fountain of living waters.

And in that day living waters will flow out from Jerusalem, half of them to the eastern sea (Dead Sea) and half of them to the western sea (the Mediterranean); it will be in summer as well as in winter.
