“Then he set out and went to Samaria. On the way, when he was at Beth-eked of the Shepherds, King Jehu met relatives of King Ahaziah of Judah. He said. ‘Who are you?’ They answered. ‘We are the kinsmen of King Ahaziah. We have come down to visit the royal princes and the sons of the queen mother.’ He said. ‘Take them alive.’ They took them alive. They killed them at the pit of Beth-eked, forty-two persons. He spared none of them.”
On his way to Samaria, King Jehu met some relatives of late King Ahaziah of Judah, thus relatives of the late King Jehoram. They were on their way to visit the Queen mother, Jezebel. There were 42 of them. First he wanted them alive. Then he killed them at Beth-eked, which is only mentioned here and not in any other biblical literature. Watch out if you had anything to do with King Ahab, Jezebel, King Ahaziah or King Jehoram.
