2 Chronicles 13:12-15

12God is with us; he is our leader. His priests with their trumpets will sound the battle cry against you. People of Israel, do not fight against the Lord, the God of your ancestors, for you will not succeed.” 13Now Jeroboam had sent troops around to the rear, so that while he was in front of Judah the ambush was behind them. 14Judah turned and saw that they were being attacked at both front and rear. Then they cried out to the Lord. The priests blew their trumpets 15and the men of Judah raised the battle cry. At the sound of their battle cry, God routed Jeroboam and all Israel before Abijah and Judah.
