1 Kings 16:9-11

Revised Standard Version

⁹ But his servant Zimri, commander of half his chariots, conspired against him. When he was at Tirzah, drinking himself drunk in the house of Arza, who was over the household in Tirzah, ¹⁰ Zimri came in and struck him down and killed him, in the twenty-seventh year of Asa king of Judah, and reigned in his stead.

¹¹ When he began to reign, as soon as he had seated himself on his throne, he killed all the house of Ba′asha; he did not leave him a single male of his kinsmen or his friends.
