1 Kings 16:9-10

16:9 His servant Zimri, a commander of half of his chariot force, conspired against him. While Elah was drinking heavily at the house of Arza, who supervised the palace in Tirzah, 16:10 Zimri came in and struck him dead. (This happened in the twenty-seventh year of Asa’s reign over Judah.) Zimri replaced Elah as king.
