2 Kings 10:12-13
12-13That done, he brushed himself off and set out for Samaria. Along the way, at Beth Eked (Binding House) of the Shepherds, he met up with some relatives of Ahaziah king of Judah.
Jehu said, "Who are you?"
They said, "We're relatives of Ahaziah and we've come down to a reunion of the royal family."
14"Grab them!" ordered Jehu. They were taken and then massacred at the well of Beth Eked. Forty-two of them—no survivors.
