2 Chronicles 25:11-14

11And Amaziah strengthened himself, and led forth his people, and went to the valley of salt, and smote of the children of Seir ten thousand. 12And other ten thousand left alive the children of Judah carried away captive, and brought them to the top of the rock, and cast them down from the top of the rock, that they were all broken in pieces. 13But the soldiers of the army whom Amaziah sent back, that they should not go with him to battle, fell upon the cities of Judah, from Samaria even to Bethhoron, and smote three thousand of them, and took much spoil.1

14Now it came to pass, after that Amaziah had come from the slaughter of the Edomites, that he brought the gods of the children of Seir, and set them up to be his gods, and bowed himself before them, and burned incense to them.
