2 Chronicles 13:10-18

But as for us, the LORD is our God, and we have not forsaken him; and the priests, which minister unto the LORD, are the sons of Aaron, and the Levites wait upon their business: and they burn unto the LORD every morning and every evening burnt sacrifices and sweet incense: the shewbread also set they in order upon the pure table; and the candlestick of gold with the lamps thereof, to burn every evening: for we keep the charge of the LORD our God; but ye have forsaken him. And, 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. But Jeroboam caused an ambushment to come about behind them: so they were before Judah, and the ambushment was behind them. And when Judah looked back, behold, the battle was before and behind: and they cried unto the LORD, and the priests sounded with the trumpets. Then 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. And the children of Israel fled before Judah: and God delivered them into their hand. And Abijah and his people slew them with a great slaughter: so there fell down slain of Israel five hundred thousand chosen men. Thus the children of Israel were brought under at that time, and the children of Judah prevailed, because they relied upon the LORD God of their fathers.
