2 Chronicles 13:12-16

12And, behold, God himself is with us for our captain, and his priests with sounding trumpets to cry alarm against you. O children of Israel, fight ye not against the Lord God of your fathers; for ye shall not prosper.

13But Jeroboam caused an ambushment to come about behind them: so they were before Judah, and the ambushment was behind them. 14And when Judah looked back, behold, the battle was before and behind: and they cried unto the Lord, and the priests sounded with the trumpets. 15Then the men of Judah gave a shout: and as the men of Judah shouted, it came to pass, that God smote Jeroboam and all Israel before Abijah and Judah. 16And the children of Israel fled before Judah: and God delivered them into their hand.
