2 Chronicles 25:11-14

11Amaziah, however, summoned his strength and led his troops to the Valley of Salt, where he struck down 10,000 men of Seir, 12and the army of Judah also captured 10,000 men alive. They took them to the top of a cliff and threw them down so that all were dashed to pieces.

13Meanwhile the troops that Amaziah had dismissed from battle raided the cities of Judah, from Samaria to Beth-horon. They struck down 3,000 people and carried off a great deal of plunder.

14When Amaziah returned from the slaughter of the Edomites, he brought back the gods of the Seirites, set them up as his own gods, bowed before them, and burned sacrifices to them.
