II Chronicles 13:8-18

And now you think to withstand the kingdom of the LORD, which is in the hand of the sons of David; and you are a great multitude, and with you are the gold calves which Jeroboam made for you as gods. Have you not cast out the priests of the LORD, the sons of Aaron, and the Levites, and made for yourselves priests, like the peoples of other lands, so that whoever comes to consecrate himself with a young bull and seven rams may be a priest of things that are not gods? But as for us, the LORD is our God, and we have not forsaken Him; and the priests who minister to the LORD are the sons of Aaron, and the Levites attend to their duties. And they burn to the LORD every morning and every evening burnt sacrifices and sweet incense; they also set the showbread in order on the pure gold table, and the lampstand of gold with its lamps to burn every evening; for we keep the command of the LORD our God, but you have forsaken Him. Now look, God Himself is with us as our head, and His priests with sounding trumpets to sound the alarm against you. O children of Israel, do not fight against the LORD God of your fathers, for you shall not prosper!” But Jeroboam caused an ambush to go around behind them; so they were in front of Judah, and the ambush was behind them. And when Judah looked around, to their surprise the battle line was at both front and rear; and they cried out to the LORD, and the priests sounded the trumpets. Then the men of Judah gave a shout; and as the men of Judah shouted, it happened that God struck Jeroboam and all Israel before Abijah and Judah. And the children of Israel fled before Judah, and God delivered them into their hand. Then Abijah and his people struck them with a great slaughter; so five hundred thousand choice men of Israel fell slain. Thus the children of Israel were subdued at that time; and the children of Judah prevailed, because they relied on the LORD God of their fathers.
