1 Kings 16:15 KJV

13For all the sins of Baasha, and the sins of Elah his son, by which they sinned, and by which they made Israel to sin, in provoking the LORD God of Israel to anger with their vanities.

14Now the rest of the acts of Elah, and all that he did, are they not written in the book of the chronicles of the kings of Israel?

15In the twenty and seventh year of Asa king of Judah did Zimri reign seven days in Tirzah. And the people were encamped against Gibbethon, which belonged to the Philistines.

16And the people that were encamped heard say, Zimri hath conspired, and hath also slain the king: wherefore all Israel made Omri, the captain of the host, king over Israel that day in the camp.

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