But a man of God came to the king and said, "O king, do not hire troops from Israel, for the LORD is not with Israel. He will not help those people of Ephraim!
If you let them go with your troops into battle, you will be defeated no matter how well you fight. God will overthrow you, for he has the power to help or to frustrate."
Amaziah asked the man of God, "But what should I do about the silver I paid to hire the army of Israel?" The man of God replied, "The LORD is able to give you much more than this!"
So Amaziah discharged the hired troops and sent them back to Ephraim. This made them angry with Judah, and they returned home in a great rage.
