2 Chronicles 13:16

But Jeroboam caused an ambush to come about behind them; so they were before Judah, and the ambush was behind them.

When Judah looked back, behold, the battle was before and behind them; and they cried to the LORD, and the priests sounded with the trumpets.

Then the men of Judah gave a shout. As the men of Judah shouted, God struck Jeroboam and all Israel before Abijah and Judah.

Abijah and his people killed them with a great slaughter, so five hundred thousand chosen men of Israel fell down slain.

Thus the children of Israel were brought under at that time, and the children of Judah prevailed, because they relied on the LORD, the God of their fathers.

Abijah pursued Jeroboam, and took cities from him: Bethel with its villages, Jeshanah with its villages, and Ephron with its villages.
