'Fountain of Living Waters' in the Bible

For my people have committed two evils: they have forsaken me, the fountain of living waters, to hew them out cisterns, broken cisterns that hold no water.

Thou hope of Israel, Jehovah! all that forsake thee shall be ashamed. They that depart from me shall be written in the earth; because they have forsaken Jehovah, the fountain of living waters.
