Omri became king of Israel during the thirty-first year Asa was king of Judah. Omri ruled Israel for twelve years, six of those years in the city of Tirzah.
So during Asa’s twenty-seventh year as king of Judah, Zimri became king of Israel and ruled in Tirzah seven days. The army of Israel was camped near Gibbethon, a Philistine town.
Then Menahem son of Gadi came up from Tirzah to Samaria and attacked Shallum son of Jabesh in Samaria. He killed him and became king in Shallum’s place.
