1 Kings 12:18-19
18-19When King Rehoboam next sent out Adoniram, head of the workforce, the Israelites ganged up on him, pelted him with stones, and killed him. King Rehoboam jumped in his chariot and fled to Jerusalem as fast as he could. Israel has been in rebellion against the Davidic regime ever since.
Jeroboam of Israel
20When the word was out that Jeroboam was back and available, the assembled people invited him and inaugurated him king over all Israel. The only tribe left to the Davidic dynasty was Judah.
