2 Chronicles 25:7-10

7But a man of God came to him, saying, “O king, do not let this army of Israel go with you, for the Lord is not with Israel nor with any of the sons of Ephraim.

8But if you do go [in spite of this warning], be strong and courageous for battle; yet God will cause you to stumble and fall before the enemy, for God has power to help and to cause people to stumble.”

9Amaziah said to the man of God, “But what shall we do about the hundred talents which I gave to the troops of Israel?” The man of God answered, “The Lord is able to give you much more than this.”

10So Amaziah dismissed the troops that came to him from Ephraim, to go home. So their anger was kindled and burned greatly against Judah, and they returned home in the heat of anger.
