He showed me: behold, the Lord was standing beside a wall built with a plumb line, with a plumb line in his hand.
And the LORD said to me, "Amos, what do you see?" And I said, "A plumb line." Then the Lord said, "Behold, I am setting a plumb line in the midst of my people Israel; I will never again pass by them;
the high places of Isaac shall be made desolate, and the sanctuaries of Israel shall be laid waste, and I will rise against the house of Jerobo'am with the sword."
