In the twenty-seventh year of Asa king of Judah, Zimri reigned seven days in Tirzah. Now the troops were encamped against Gibbethon, which belonged to the Philistines.
Baasha the son of Ahijah of the house of Issachar conspired against him, and Baasha killed him at Gibbethon, which belonged to the Philistines, for Nadab and all Israel laid siege to Gibbethon.
The troops who were encamped heard how Zimri had conspired and had slain the king. As a result, all Israel made Omri, the commander of the army, king over Israel that day in the camp.
