'Fountain' in the Bible

{Oh that my head were waters}, and my eyes a fountain of tears, so that I might weep day and night, [for] the slain of the daughter of my people.

Yahweh, the hope of Israel, all [those who] forsake you will be put to shame, and [those who] turn aside from you in the earth will be recorded, for they have forsaken the fountain of living water, Yahweh.

{Therefore} thus says Yahweh, "Look, I [am] going to contend your case, and I will avenge your vengeance, and I will cause her sea to dry up, and I will cause her fountain to dry up.
