2 Kings 10:17-21
English Standard Version
18Then Jehu assembled all the people and said to them, "Ahab served Baal a little, but Jehu will serve him much.
19Now therefore call to me all the prophets of Baal, all his worshipers and all his priests. Let none be missing, for I have a great sacrifice to offer to Baal. Whoever is missing shall not live." But Jehu did it with cunning in order to destroy the worshipers of Baal.
20And Jehu ordered, "Sanctify a solemn assembly for Baal." So they proclaimed it.
21And Jehu sent throughout all Israel, and all the worshipers of Baal came, so that there was not a man left who did not come. And they entered the house of Baal, and the house of Baal was filled from one end to the other.
