II Kings 10:10-11, 31

Know now that nothing shall fall to the earth of the word of the LORD which the LORD spoke concerning the house of Ahab; for the LORD has done what He spoke by His servant Elijah.” So Jehu killed all who remained of the house of Ahab in Jezreel, and all his great men and his close acquaintances and his priests, until he left him none remaining.

But Jehu took no heed to walk in the law of the LORD God of Israel with all his heart; for he did not depart from the sins of Jeroboam, who had made Israel sin.
