Context Reading
15Then the men of Judah gave a shout. As the men of Judah shouted, God struck Jeroboam and all Israel before Abijah and Judah. 16The children of Israel fled before Judah, and God delivered them into their hand. 17Abijah and his people killed them with a great slaughter, so five hundred thousand chosen men of Israel fell down slain. 18Thus the children of Israel were brought under at that time, and the children of Judah prevailed, because they relied on Yahweh, the God of their fathers. 19Abijah pursued Jeroboam, and took cities from him: Bethel with its villages, Jeshanah with its villages, and Ephron with its villages.
