1 Kings 16:9-13

9His 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,

10Zimri came in and struck him dead. (This happened in the twenty-seventh year of Asa’s reign over Judah.) Zimri replaced Elah as king.

11When 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.

12Zimri destroyed Baasha’s entire family, just as the Lord had predicted to Baasha through Jehu the prophet.

13This happened because of all the sins which Baasha and his son Elah committed and which they made Israel commit. They angered the Lord God of Israel with their worthless idols.
