2 Chronicles 25: Against Edom

Edom (a nation descended from Esau, the twin brother of Jacob) was often at odds with Judah. Since the land of the Edomites was so near, it was easy for them to cause trouble. Amaziah got an army ready, listened to a prophet, and won the battle. But (here we go again!) be brought their idols back home and made them his gods. His reign got worse until he was murdered by conspirators. What does it take for us to learn that God punishes sin?
