1 Kings 16:9-13

9However, while Elah was in Tirzah getting drunk in the house of Arza the steward of his household there, Elah’s servant Zimri, the commander of half his chariots, conspired against him. 10So in the twenty-seventh year of Asa’s reign over Judah, Zimri went in, struck Elah down, and killed him. And Zimri reigned in his place.

11As soon as Zimri began to reign and was seated on the throne, he struck down the entire household of Baasha. He did not leave a single male, whether a kinsman or friend. 12So Zimri destroyed the entire household of Baasha, according to the word that the LORD had spoken against Baasha through Jehu the prophet. 13This happened because of all the sins Baasha and his son Elah had committed and had caused Israel to commit, provoking the LORD, the God of Israel, to anger with their worthless idols.
