2 Kings 10:18-19
18-19Next, Jehu got all the people together and addressed them:
Ahab served Baal small-time; Jehu will serve him big-time.
"Get all the prophets of Baal here—everyone who served him, all his priests. Get everyone here; don't leave anyone out. I have a great sacrifice to offer Baal. If you don't show up, you won't live to tell about it." (Jehu was lying, of course. He planned to destroy all the worshipers of Baal.)
20Jehu ordered, "Make preparation for a holy convocation for Baal." They did and posted the date.
