2 Chronicles 25:7-10

7 But 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—all these Ephraimites.
8 Rather, go by yourself and act; be strong in battle, or God will fling you down before the enemy; for God has power to help or to overthrow."
9 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."
10 Then Amaziah discharged the army that had come to him from Ephraim, letting them go home again. But they became very angry with Judah, and returned home in fierce anger.
