1 Kings 18:39-40

When all the people saw it, they fell face downward; and they said, “The LORD, He is God! The LORD, He is God!” Then Elijah said to them, “Seize the prophets of Baal; do not let one of them escape.” They seized them; and Elijah brought them down to the brook Kishon, and [as God’s law required] killed them there. [Deut 13:5, 12-15; 18:20]
