1 Kings 15:29-30

29And it was so, when he became king, that he killed all the house of Jeroboam. He did not leave to Jeroboam anyone that breathed, until he had destroyed him, according to the word of the Lord which He had spoken by His servant Ahijah the Shilonite,

30because of the sins of Jeroboam, which he had sinned and by which he had made Israel sin, because of his provocation with which he had provoked the Lord God of Israel to anger.
