2 Chronicles 13:8-18

“And now you intend to assert yourselves against the kingdom of the LORD which is in the hands of the sons of David, since you are a great multitude and have with you the golden calves (idols) which Jeroboam made for you as gods. Have you not driven out the priests of the LORD, the sons of Aaron and the Levites, and made priests for yourselves like the peoples of other lands? So whoever comes to consecrate himself with a young bull and seven rams, even he may become a priest of non-existent gods (idols). But as for us, the LORD is our God, and we have not abandoned (turned away from) Him. The sons of Aaron are ministering to the LORD as priests, and the Levites attend to their service. Every morning and every evening they offer the burnt offerings and the fragrant incense to the LORD; and the showbread is set on the clean table [of pure gold], and the golden lampstand with its lamps is ready to light every evening; for we keep the charge of the LORD our God [that is, the obligation we have to Him], but you have abandoned (turned away from) Him. Behold, God is with us at our head, and His priests [are here] with their signal trumpets to sound an alarm against you. O sons of Israel, do not fight against the LORD God of your fathers, for you cannot 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 [the men of] Judah turned around, they were attacked from both front and rear; so they cried out to the LORD [for help], and the priests blew the trumpets. Then the men of Judah raised a war cry; and as they shouted, God struck Jeroboam and all Israel [with defeat] before Abijah and Judah. And the sons of Israel fled before Judah, and God handed over the sons of Israel to them. Abijah and his people inflicted on them a great defeat, so that 500,000 chosen men of Israel fell slain. Thus the sons of Israel were subdued (humbled) at that time, and the sons of Judah prevailed because they relied on the LORD, the God of their fathers.
