2 Kings 10:30-31

30The Lord said to Jehu, “Because you have done well in accomplishing what is right in my eyes and have done to the house of Ahab all I had in mind to do, your descendants will sit on the throne of Israel to the fourth generation.” 31Yet Jehu was not careful to keep the law of the Lord, the God of Israel, with all his heart. He did not turn away from the sins of Jeroboam, which he had caused Israel to commit.
