'Living Water' in the Bible

For My people have committed a double evil:They have abandoned Me,the fountain of living water,and dug cisterns for themselves,cracked cisterns that cannot hold water.

Lord, the hope of Israel,all who abandon Youwill be put to shame.All who turn away from Mewill be written in the dirt,for they have abandonedthe Lord, the fountain of living water.

On that day living water will flow out from Jerusalem, half of it toward the eastern sea and the other half toward the western sea, in summer and winter alike.
