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.)
20 Then Jehu ordered, “Proclaim a day of worship in honour of Baal!” The proclamation was made,
21 and Jehu sent word throughout all the land of Israel. All who worshipped Baal came; not one of them failed to come. They all went into the temple of Baal, filling it from one end to the other.
