1. This will not happen either (1-6)
The LORD gave Amos three visions. In the first, Amos saw a swarm of locusts strip the land clean after the king's harvest. Knowing the suffering this would cause the people, Amos begged the LORD for forgiveness. God relented. In the second vision, Amos saw the LORD bring terrible fire that dried up the sea and burned up the land. Amos cried out for mercy again and again, God relented.
2. A vision of a plumb line (7-9)
Amos had a third vision of the LORD standing by a wall. The wall had been built straight and true. The LORD measured it with a plumb line. The wall symbolized Israel who had once followed God's word and standard. But when God measured them in the present, they were far from plumb. Time for repentance had run out. God would spare them no longer. God would destroy the kingdom of Israel.
