2 Chronicles 25:7-10

7But a man of God came to him and said, “Your Majesty, do not hire troops from Israel, for the Lord is not with Israel. He will not help those people of Ephraim!

8If you let them go with your troops into battle, you will be defeated by the enemy no matter how well you fight. God will overthrow you, for he has the power to help you or to trip you up.”

9Amaziah asked the man of God, “But what about all that 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!”

10So Amaziah discharged the hired troops and sent them back to Ephraim. This made them very angry with Judah, and they returned home in a great rage.
