2 Kings 10:16-19 Living Bible (TLB)
16 “Now come along with me,” Jehu said, “and see how much I have done for the Lord.” So Jehonadab rode along with him. 17 When he arrived in Samaria he butchered all of Ahab’s friends and relatives, just as Elijah, speaking for the Lord, had predicted.
Then Jehu called a meeting of all the people of the city and said to them, “Ahab hardly worshiped Baal at all in comparison to the way I am going to! 18-19 Summon all the prophets and priests of Baal, and call together all his worshipers. See to it that every one of them comes, for we worshipers of Baal are going to have a great celebration to praise him. Any of Baal’s worshipers who don’t come will be put to death.”
But Jehu’s plan was to exterminate them.
