1 Kings 16:17-22

17So Omri led the entire army of Israel up from Gibbethon to attack Tirzah, Israel’s capital.

18When Zimri saw that the city had been taken, he went into the citadel of the palace and burned it down over himself and died in the flames.

19For he, too, had done what was evil in the Lord’s sight. He followed the example of Jeroboam in all the sins he had committed and led Israel to commit.

20The rest of the events in Zimri’s reign and his conspiracy are recorded in The Book of the History of the Kings of Israel.

21But now the people of Israel were split into two factions. Half the people tried to make Tibni son of Ginath their king, while the other half supported Omri.

22But Omri’s supporters defeated the supporters of Tibni. So Tibni was killed, and Omri became the next king.
