2 Chronicles 13:14-18

14When [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.

15Then the men of Judah raised a war cry; and as they shouted, God struck Jeroboam and all Israel [with defeat] before Abijah and Judah.

16And the sons of Israel fled before Judah, and God handed over the sons of Israel to them.

17Abijah and his people inflicted on them a great defeat, so that 500,000 chosen men of Israel fell slain.

18Thus 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.
