2 Chronicles 13:18 (KJV)

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.

And Abijah pursued after Jeroboam, and took cities from him, Bethel with the towns thereof, and Jeshanah with the towns thereof, and Ephraim with the towns thereof.

Neither did Jeroboam recover strength again in the days of Abijah: and the LORD struck him, and he died.

But Abijah waxed mighty, and married fourteen wives, and begat twenty and two sons, and sixteen daughters.

And the rest of the acts of Abijah, and his ways, and his sayings, are written in the story of the prophet Iddo.
