2 Kings 10:10-14

10:10 Therefore take note that not one of the judgments the Lord announced against Ahab’s dynasty has failed to materialize. The Lord had done what he announced through his servant Elijah.” 10:11 Then Jehu killed all who were left of Ahab’s family in Jezreel, and all his nobles, close friends, and priests. He left no survivors.

10:12 Jehu then left there and set out for Samaria. While he was traveling through Beth Eked of the Shepherds, 10:13 Jehu encountered the relatives of King Ahaziah of Judah. He asked, “Who are you?” They replied, “We are Ahaziah’s relatives. We have come down to see how the king’s sons and the queen mother’s sons are doing.” 10:14 He said, “Capture them alive!” So they captured them alive and then executed all forty-two of them in the cistern at Beth Eked. He left no survivors.
