2 Kings 10:30-31
10:30 The Lord said to Jehu, “You have done well. You have accomplished my will and carried out my wishes with regard to Ahab’s dynasty. Therefore four generations of your descendants will rule over Israel.”
10:31 But Jehu did not carefully and wholeheartedly obey the law of the Lord God of Israel. He did not repudiate the sins which Jeroboam had encouraged Israel to commit.
