Jeremiah 6:7

"As a well casteth forth its waters, so she casteth forth her wickedness: violence and destruction are found in her; before me continually is sickness and wounds. Be thou instructed, O Jerusalem, lest my soul be alienated from thee; lest I make thee a desolation, a land not inhabited."

The meaning of Jeremiah 6:7 is that, "just as a water well maintained its waters at a constant level, no matter how much was taken out of it; in the same way Jerusalem maintained its full level of producing wickedness, violence, and destruction, continually.

"Be thou instructed, O Jerusalem ..." (Jeremiah 6:8) "This seems to indicate that the tragedy might be averted if the people would repent."[9] Maybe the passage does indicate such a thing; but, even if it does, it was purely a theoretical premise suggested by the prophet. Not only did Israel not repent, they despised and rejected God's law.
