Amos 7:7-9

Thus He showed me, and behold, the Lord was standing by a vertical wall with a plumb line in His hand. The LORD said to me, “What do you see, Amos?” And I said, “A plumb line.” Then the Lord said, “Behold I am about to put a plumb line In the midst of My people Israel. I will spare them no longer. The high places of Isaac will be desolated And the sanctuaries of Israel laid waste. Then I will rise up against the house of Jeroboam with the sword.”
