2 Chronicles 25:8-12

But if you do go, do it, be strong for the battle; yet God will bring you down before the enemy, for God has the power to help and to bring down.”

Amaziah said to the man of God, “But what are we to do about the hundred talents which I have given to the troops of Israel?” And the man of God answered, “The Lord has much more to give you than this.”

Then Amaziah dismissed the troops which came to him from Ephraim, to go home; so their anger burned against Judah, and they returned home in fierce anger.

Now Amaziah gathered his courage and led his people out, and went to the Valley of Salt, and struck and killed ten thousand of the sons of Seir.

The sons of Judah also captured ten thousand alive and brought them to the top of the cliff, and threw them down from the top of the cliff so that they were all dashed to pieces.
