15 The Lord was angry at Amaziah and sent a prophet to him, who said, “Why are you following these gods that could not deliver their own people from your power?”
16 While he was speaking, Amaziah said to him, “Did we appoint you to be a royal counselor? Stop prophesying or else you will be killed!” So the prophet stopped, but added, “I know that the Lord has decided to destroy you, because you have done this thing and refused to listen to my advice.”
17 After King Amaziah of Judah consulted with his advisers, he sent this message to the king of Israel, Joash son of Jehoahaz, the son of Jehu, “Come, face me on the battlefield.”
18 King Joash of Israel sent this message back to King Amaziah of Judah, “A thorn bush in Lebanon sent this message to a cedar in Lebanon, ‘Give your daughter to my son as a wife.’ Then a wild animal of Lebanon came by and trampled down the thorn bush.
19 You defeated Edom and it has gone to your head. Gloat over your success, but stay in your palace. Why bring calamity on yourself? Why bring down yourself and Judah along with you?”
20 But Amaziah did not heed the warning, for God wanted to hand them over to Joash because they followed the gods of Edom.
21 So King Joash of Israel attacked. He and King Amaziah of Judah faced each other on the battlefield in Beth Shemesh of Judah.
