Amos told everyone, God showed me possible futures. First, God showed me a swarm of locusts eating up the harvests and everyone starving. I begged it not to do that to us. So It said It wouldn’t. Then It showed me a wildfire burning up Israel, and again I begged It to please not let that happen. And God said It wouldn’t. Later it showed me a really straight tall wall, and asked, what do you see? And I answered, a wall. And It was, Exactly. This wall means that I will spare Israel no longer. It will be destroyed.
Because Amos went around telling people stuff like this, the priest Amaziah sent a letter complaining to King Jeroboam that Amos was a troublemaker. On the king’s authority, Amaziah told Amos to get the hell out of Israel and go back to Judah. Amos was all, Look, I’m just a shepherd. But God commanded me to come to Israel to tell you all these things. And It tells me I have to stay and continue. So for trying to stop me, God will curse you. Your wife will become a whore and you children will be murdered. Your land will be stolen and you will be sent into exile with the rest of the Israelites.
