2 Kings 10:30

Though the Lord said to Jehu, Because thou hast taken a pleasure in doing what is right in My sight, and hast done to the house of Achab according to all that was in My heart, thy children of the fourth generation shall sit on the throne of Israel,

And the Lord said to Ju, Because of all thy deeds wherein thou hast acted well in doing that which was right in my eyes, according to all things which thou hast done to the house of Achaab as they were in my heart, thy sons to the fourth generation shall sit upon the throne of Israel.
