I Kings 18:19, 40

Now therefore, send and gather all Israel to me on Mount Carmel, the four hundred and fifty prophets of Baal, and the four hundred prophets of Asherah, who eat at Jezebel’s table.”

And Elijah said to them, “Seize the prophets of Baal! Do not let one of them escape!” So they seized them; and Elijah brought them down to the Brook Kishon and executed them there.
