1 Kings 16:9-11

American Standard Version

⁹ And his servant Zimri, captain of half his chariots, conspired against him. Now he was in Tirzah, drinking himself drunk in the house of Arza, who was over the household in Tirzah: ¹⁰ and Zimri went in and smote him, and killed him, in the twenty and seventh year of Asa king of Judah, and reigned in his stead. ¹¹ And it came to pass, when he began to reign, as soon as he sat on his throne, that he smote all the house of Baasha: he left him not a single man-child, neither of his kinsfolks, nor of his friends.
