1 Kings 16:9-12
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.
16:11 When he became king and occupied the throne, he killed Baasha’s entire family. He did not spare any male belonging to him; he killed his relatives and his friends.
16:12 Zimri destroyed Baasha’s entire family, just as the Lord had predicted to Baasha through Jehu the prophet.
