1 Kings 16:18-19

18And it happened, when Zimri saw that the city was taken, that he went into the citadel of the king’s house and burned the king’s house down upon himself with fire, and died,

19because of the sins which he had committed in doing evil in the sight of the Lord, in walking in the way of Jeroboam, and in his sin which he had committed to make Israel sin.
