1 Kings 16:9-11

9His servant 1Zimri, commander of half his chariots, conspired against him. Now he was at Tirzah drinking himself drunk in the house of Arza, 2who was over the household at Tirzah. 10Then Zimri went in and struck him and put him to death in the twenty-seventh year of Asa king of Judah, and became king in his place. 11It came about when he became king, as soon as he sat on his throne, that 3he 4killed all the household of Baasha; he did not leave 5a single male, neither of his 6relatives nor of his friends.
