1 Kings 16:9-10

Zimri, one of Elah’s officers, commanded half of Elah’s chariots. Zimri made plans against Elah while the king was in Tirzah, getting drunk at Arza’s home. (Arza was in charge of the palace at Tirzah.) Zimri went into Arza’s house and killed Elah during Asa’s twenty-seventh year as king of Judah. Then Zimri became king of Israel in Elah’s place.
