Amos 7:7-9

7Then he showed me another vision. I saw the Lord standing beside a wall that had been built using a plumb line. He was using a plumb line to see if it was still straight.

8And the Lord said to me, “Amos, what do you see?” I answered, “A plumb line.” And the Lord replied, “I will test my people with this plumb line. I will no longer ignore all their sins.

9The pagan shrines of your ancestors will be ruined, and the temples of Israel will be destroyed; I will bring the dynasty of King Jeroboam to a sudden end.”
