2Kgs 10:19-20

19Now therefore summon 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 was acting with cunning in order to destroy the worshipers of Baal.20Jehu decreed, “Sanctify a solemn assembly for Baal.” So they proclaimed it.
