'Fountain' in the Bible

“For My people have committed two evils:They have abandoned (rejected) Me,The fountain of living water,And they have carved out their own cisterns,Broken cisternsThat cannot hold water.

“As a fountain springs up and pours out its fresh waters,So she [continually] pours out her fresh wickedness.Violence and destruction are heard inside her [walls];Sickness and wounds are always before Me.

O Lord, the hope of Israel,All who abandon You will be shamed.Those who turn away on earth will be written down,Because they have abandoned the Lord, the fountain of living waters.

Therefore thus says the Lord,“Behold, I will plead your caseAnd take full vengeance for you;I will dry up her sea and great reservoirAnd make her fountain dry.
