What does 2 Chronicles 25:17 mean?

Now after Amaziah had come from the slaughter of the Edomites, he brought the gods of the children of Seir, and set them up to be his gods, and bowed down himself before them, and burned incense to them.

Therefore Yahweh’s anger burned against Amaziah, and he sent to him a prophet, who said to him, “Why have you sought after the gods of the people, which have not delivered their own people out of your hand?”

As he talked with him, the king said to him, “Have we made you one of the king’s counselors? Stop! Why should you be struck down?” Then the prophet stopped, and said, “I know that God has determined to destroy you, because you have done this, and have not listened to my counsel.”

Joash king of Israel sent to Amaziah king of Judah, saying, “The thistle that was in Lebanon sent to the cedar that was in Lebanon, saying, ‘Give your daughter to my son as his wife. Then a wild animal that was in Lebanon passed by, and trampled down the thistle.

You say to yourself that you have struck Edom; and your heart lifts you up to boast. Now stay at home. Why should you meddle with trouble, that you should fall, even you, and Judah with you?’”

But Amaziah would not listen; for it was of God, that he might deliver them into the hand of their enemies, because they had sought after the gods of Edom.
