2 Chronicles 25:11-14

11Now Amaziah took courage and led his people out to the Valley of Salt, and he struck down 10,000 of the men of Seir (Edom).

12The sons of Judah also captured 10,000 alive and brought them to the top of the cliff. They threw them down from the top of the cliff and they were all crushed to pieces.

13But the troops whom Amaziah sent back, those not allowed to go with him to battle, attacked and raided the cities of Judah, from Samaria to Beth-horon, and struck down 3,000 men and took a large amount of spoil.

14After Amaziah came back from the slaughter of the Edomites, he brought the gods of the sons of Seir, and set them up to be his gods, bowed before them, and burned incense to them.
