Jehu kills Baal worshippers

15 Jehu departed from there and encountered Rechab's son Jehonadab. Jehu greeted him, and asked, "Are you as committed to me as I am to you?" Jehonadab responded, "Yes, I am." "If so," said Jehu, "then give me your hand." So Jehonadab put out his hand, and Jehu pulled him up into the chariot.
