King Amaziah of Judah had just won a battle against the Edomites after sending 100,000 Israelite mercenaries back to Israel on the advice of an unnamed man of God. Inexplicably, he brought back their idols with him and set them up for himself, worshiping them and sacrificing to them.
Another unnamed prophet brings him God’s mocking anger: “Why would you worship these gods who couldn’t even save their own people?” King Amaziah responds by threatening to kill the prophet, and the prophet responds by promising God would destroy him.
Sure enough, Amaziah goes to war against Israel and loses badly. Israel kidnaps Amaziah, destroys part of Jerusalem’s wall, and seizes treasure from the temple and the palace.
