2 Chronicles 13:17,18 (KJV)
17 And Abijah and his people slew them with a great slaughter: so there fell down slain of Israel five hundred thousand chosen men.
18 Thus the children of Israel were brought under at that time, and the children of Judah prevailed, because they relied upon the Lord God of their fathers.
2 Chronicles 13
Do Not Fight Against God And His People
God’s people were surrounded with no way out, but to call upon the Lord God in prayer. Even their trumpets sounded, in order to get people’s attention that God is their deliverer.
