And it came to pass, when he reigned, that he smote all the house of Jeroboam; he left not to Jeroboam any that breathed, until he had destroyed him, according unto the saying of the LORD, which he spake by his servant Ahijah the Shilonite:
When he reigned ... he smote all the house of Jeroboam. It was according to a barbarous practice, too common in the East, for a usurper to extirpate all rival candidates for the throne; but it was an accomplishment of Ahijah's prophecy concerning Jeroboam (1 Kings 14:10-11).
