'Fountain of Living Waters' in the Bible

For my people have done two evils; they have given up me, the fountain of living waters, and have made for themselves water-holes, cut out from the rock, broken water-holes, of no use for storing water.

O Lord, the hope of Israel, all who give you up will be put to shame; those who go away from you will be cut off from the earth, because they have given up the Lord, the fountain of living waters.
