'Fountain of Life' in the Bible

"Do so because my people have committed a double wrong: they have rejected me, the fountain of life-giving water, and they have dug cisterns for themselves, cracked cisterns which cannot even hold water."

You are the one in whom Israel may find hope. All who leave you will suffer shame. Those who turn away from you will be consigned to the nether world. For they have rejected you, the Lord, the fountain of life.
