1 Kings 16:21 KJV

19For his sins which he sinned in doing evil in the sight of the LORD, in walking in the way of Jeroboam, and in his sin which he did, to make Israel to sin.

20Now the rest of the acts of Zimri, and his treason that 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 prevailed against the people that followed Tibni the son of Ginath: so Tibni died, and Omri reigned.

23In the thirty and first year of Asa king of Judah began Omri to reign over Israel, twelve years: six years reigned he in Tirzah.
