2 Chronicles 13:14-18

14And 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.

15Then 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.

16And the children of Israel fled before Judah, and God delivered them into their hand.

17Then Abijah and his people struck them with a great slaughter; so five hundred thousand choice men of Israel fell slain.

18Thus 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.
