2 Chronicles 13:5-7, 17

Do you not know that the LORD God of Israel gave the rule over Israel forever to David and his sons by a covenant of salt? Yet Jeroboam the son of Nebat, the servant of Solomon the son of David, rose up and rebelled against his master, and worthless men gathered about him, scoundrels, who proved too strong for Rehoboam, the son of Solomon, when he was young and timid and could not hold his own against them.

Abijah and his people defeated them with a great slaughter, so that 500,000 chosen men of Israel fell slain.
