2 Chronicles 13:14-15

13:14 The men of Judah turned around and realized they were being attacked from the front and the rear. So they cried out for help to the Lord. The priests blew their trumpets, 13:15 and the men of Judah gave the battle cry. As the men of Judah gave the battle cry, the Lord struck down Jeroboam and all Israel before Abijah and Judah.
