2 Chronicles 25:10

7 But a man of God came to him, and said: O king, let not the army of Israel go out with thee, for the Lord is not with Israel, and all the children of Ephraim:

8 And if thou think that battles consist in the strength of the army, God will make thee to be overcome by the enemies: for it belongeth to God both to help, and to put to flight.

9 And Amasias said to the man of God: What will then become of the hundred talents which I have given to the soldiers of Israel? and the man of God answered him: The Lord is rich enough to be able to give thee much more than this.

10 Then Amasias separated the army, that came to him out of Ephraim, to go home again: but they being much enraged against Juda, returned to their own country.

11 And Amasias taking courage led forth his people, and went to the vale of saltpits, and slew of the children of Seir ten thousand.

12 And other ten thousand men the sons of Juda took, and brought to the steep of a certain rock, and cast them down headlong from the top, and they all were broken to pieces.

13 But that army which Amasias had sent back, that they should not go with him to battle, spread themselves among the cities of Juda, from Samaria to Beth-horon, and having killed three thousand took away much spoil.
