Thus he shewed me: and behold the Lord stood upon a wall made by a plumb-line, with a plumb-line in His hand.

And the Lord said unto me: Amos, what seest thou? and I said, A plumb-line. Then said the Lord: Behold, I will set a plumb-line in the midst of my people Israel;

I will not again pass by them any more. Amos, vii. 7, 8.
