2 Chronicles 13:8-18

“So now you intend to resist the kingdom of the LORD through the sons of David, being a great multitude and having with you the golden calves which Jeroboam made for gods for you. Have you not driven out the priests of the LORD, the sons of Aaron and the Levites, and made for yourselves priests like the peoples of other lands? Whoever comes to consecrate himself with a young bull and seven rams, even he may become a priest of what are no gods. But as for us, the LORD is our God, and we have not forsaken Him; and the sons of Aaron are ministering to the LORD as priests, and the Levites attend to their work. Every morning and evening they burn to the LORD burnt offerings and fragrant incense, and the showbread is set on the clean table, and the golden lampstand with its lamps is ready to light every evening; for we keep the charge of the LORD our God, but you have forsaken Him. Now behold, God is with us at our head and His priests with the signal trumpets to sound the alarm against you. O sons of Israel, do not fight against the LORD God of your fathers, for you will not succeed.” But Jeroboam had set an ambush to come from the rear, so that Israel was in front of Judah and the ambush was behind them. When Judah turned around, behold, they were attacked both front and rear; so they cried to the LORD, and the priests blew the trumpets. Then the men of Judah raised a war cry, and when the men of Judah raised the war cry, then it was that God routed Jeroboam and all Israel before Abijah and Judah. When the sons of Israel fled before Judah, God gave them into their hand. Abijah and his people defeated them with a great slaughter, so that 500,000 chosen men of Israel fell slain. Thus the sons of Israel were subdued at that time, and the sons of Judah conquered because they trusted in the LORD, the God of their fathers.
