1 Kings 16:17-22

17Then Omri and all Israel with him went up from Gibbethon, and they besieged Tirzah.

18And it happened, when Zimri saw that the city was taken, that he went into the citadel of the king’s house and burned the king’s house down upon himself with fire, and died,

19because of the sins which he had committed in doing evil in the sight of the Lord, in walking in the way of Jeroboam, and in his sin which he had committed to make Israel sin.

20Now the rest of the acts of Zimri, and the treason he committed, are they not written in the book of the chronicles of the kings of Israel?

21Then the people of Israel were divided into two parts: half of the people followed Tibni the son of Ginath, to make him king, and half followed Omri.

22But the people who followed Omri prevailed over the people who followed Tibni the son of Ginath. So Tibni died and Omri reigned.
