1 Kings 16:17-22

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

18And it came to pass 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 over him with fire;

19and he died for his sins which he sinned in doing evil in the sight of Jehovah, in walking in the way of Jeroboam, and in his sin which he did, making Israel to sin.

20And the rest of the acts of Zimri, and his conspiracy which he wrought, are they not written in the book of the chronicles of the kings of Israel?

21Then were the people of Israel 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 that followed Omri overcame the people that followed Tibni the son of Ginath; and Tibni died, and Omri reigned.
