1 Kings 12:16-17
12:16 When all Israel saw that the king refused to listen to them, the people answered the king, “We have no portion in David, no share in the son of Jesse! Return to your homes, O Israel! Now, look after your own dynasty, O David!” So Israel returned to their homes.
12:17 (Rehoboam continued to rule over the Israelites who lived in the cities of Judah.)
