2 Chronicles 25:6-9

6He hired also an hundred thousand mighty men of valour out of Israel for an hundred talents of silver.

7But there came a man of God to him, saying, O king, let not the army of Israel go with thee; for the LORD is not with Israel, to wit, with all the children of Ephraim.

8But if thou wilt go, do valiantly, be strong for the battle: God shall cast thee down before the enemy; for God hath power to help, and to cast down.

9And Amaziah said to the man of God, But what shall we do for the hundred talents which I have given to the army of Israel? And the man of God answered, The LORD is able to give thee much more than this.
