1 Kings 18:39-40

18:39 When all the people saw this, they threw themselves down with their faces to the ground and said, “The Lord is the true God! The Lord is the true God!” 18:40 Elijah told them, “Seize the prophets of Baal! Don’t let even one of them escape!” So they seized them, and Elijah led them down to the Kishon Valley and executed them there.
