13 he met some relatives of the late King Ahaziah of Judah and asked them, “Who are you?”“Ahaziah's relatives,” they answered. “We are going to Jezreel to pay our respects to the children of Queen Jezebel and to the rest of the royal family.”
14 Jehu ordered his men, “Take them alive!” They seized them, and he put them to death near a pit there. There were 42 people in all, and not one of them was left alive.
15 Jehu started out again, and on his way he was met by Jonadab son of Rechab. Jehu greeted him and said, “You and I think alike. Will you support me?”“I will,” Jonadab answered.“Give me your hand, then,” Jehu replied. They clasped hands, and Jehu helped him up into the chariot,
16 saying, “Come with me and see for yourself how devoted I am to the Lord.” And they rode on together to Samaria.
17 When they arrived there, Jehu killed all of Ahab's relatives, not sparing even one. This is what the Lord had told Elijah would happen.
18 Jehu called the people of Samaria together and said, “King Ahab served the god Baal a little, but I will serve him much more.
19 Call together all the prophets of Baal, all his worshippers, and all his priests. No one is excused; I am going to offer a great sacrifice to Baal, and whoever is not present will be put to death.” (This was a trick on the part of Jehu by which he meant to kill all the worshippers of Baal.)
