2 Kings 10:18-20

18Then Jehu called a meeting of all the people of the city and said to them, “Ahab’s worship of Baal was nothing compared to the way I will worship him!

19Therefore, summon all the prophets and worshipers of Baal, and call together all his priests. See to it that every one of them comes, for I am going to offer a great sacrifice to Baal. Anyone who fails to come will be put to death.” But Jehu’s cunning plan was to destroy all the worshipers of Baal.

20Then Jehu ordered, “Prepare a solemn assembly to worship Baal!” So they did.
