2 Kings 10:17

He slew all that remained unto Ahab in Samaria Either all his household, or, rather, all his kindred and relations, though more remote from him. This he did, no doubt, under pretence of zeal for God, and to fulfil the prophecy of Elijah; but there is too much reason to apprehend, from several of his actions, and, indeed, his general conduct, that in this, as well as in several of the other slaughters which he made, his chief motive was to secure the kingdom to himself and his posterity.
