10:29 However, Jehu did not repudiate the sins which Jeroboam son of Nebat had encouraged Israel to commit; the golden calves remained in Bethel and Dan.
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.”
