2 Kings 10:19-20

Now therefore call unto me all the prophets of Baal, all his servants, and all his priests; let none be wanting: for I have a great sacrifice to do to Baal; whosoever shall be wanting, he shall not live. But Jehu did it in subtilty, to the intent that he might destroy the worshippers of Baal. And Jehu said, Proclaim a solemn assembly for Baal. And they proclaimed it.
