1 Kings 16:9-10

His servant Zimri, commander of half his chariots, conspired against him while Elah was in Tirzah getting drunk in the house of Arza, who was in charge of the household at Tirzah. In the twenty-seventh year of Judah’s King Asa, Zimri went in and struck Elah down, killing him. Then Zimri became king in his place.
