Amos 7:7-9

7This is what he showed me: The Lord was standing by a wall that had been built true to plumb, with a plumb line in his hand.

8And the Lord asked me, “What do you see, Amos?” “A plumb line,” I replied. Then the Lord said, “Look, I am setting a plumb line among my people Israel; I will spare them no longer.

9“The high places of Isaac will be destroyed and the sanctuaries of Israel will be ruined; with my sword I will rise against the house of Jeroboam.”
