2 Chronicles 25:10-12

Young's Literal Translation

¹⁰ And Amaziah separateth them -- for the troop that hath come in unto him from Ephraim to go to their own place, and their anger doth burn mightily against Judah, and they turn back to their place in the heat of anger.

¹¹ And Amaziah hath strengthened himself, and leadeth his people, and goeth to the Valley of Salt, and smiteth the sons of Seir -- ten thousand.

¹² And ten thousand alive have the sons of Judah taken captive, and they bring them to the top of the rock, and cast them from the top of the rock, and all of them have been broken.
