Amos 7:7-9

Thus he shewed me: and, behold, the Lord stood upon a wall made by a plumbline, with a plumbline in his hand. And the LORD said unto me, Amos, what seest thou? And I said, A plumbline. Then said the Lord, Behold, I will set a plumbline in the midst of my people Israel: I will not again pass by them any more: and the high places of Isaac shall be desolate, and the sanctuaries of Israel shall be laid waste; and I will rise against the house of Jeroboam with the sword.
