Amos 7:7-9

7He showed me this: The Lord was standing there by a vertical wall with a plumb line in his hand.

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

9Isaac’s high places will be deserted, and Israel’s sanctuaries will be in ruins; I will rise up against the house of Jeroboam with a sword.”
