2 Chronicles 25:7-10

7But a man of God came to him and said, "O king, do not let the army of Israel go with you, for the Lord is not with Israel, with all these Ephraimites.

8But go, act, be strong for the battle. Why should you suppose that God will cast you down before the enemy? For God has power to help or to cast down."

9And Amaziah said to the man of God, "But what shall we do about the hundred talents that I have given to the army of Israel?" The man of God answered, "The Lord is able to give you much more than this."

10Then Amaziah discharged the army that had come to him from Ephraim to go home again. And they became very angry with Judah and returned home in fierce anger.
