2 Kings 10:18-20

ASV(i) 18 And Jehu gathered all the people together, and said unto them, Ahab served Baal a little; but Jehu will serve him much. 19 Now therefore call unto me all the prophets of Baal, all his worshippers, 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 subtlety, to the intent that he might destroy the worshippers of Baal. 20 And Jehu said, Sanctify a solemn assembly for Baal. And they proclaimed it.
