1 Kings 16:9-11

Complete Jewish Bible

⁹ His servant Zimri, commander of half of his chariots, plotted against him. Finally, one time when Elah was in Tirtzah, drinking himself senseless in the house of Artza, administrator of the palace in Tirtzah, ¹⁰ Zimri entered, struck him down and killed him. This was in the twenty-seventh year of Asa king of Y’hudah; Zimri then took Elah’s place as king.

¹¹ At the beginning of his reign, as soon as he took over the throne, he killed off the entire house of Ba‘sha; he left not a single male, neither of his relatives nor of his friends.
