1 Kings 18:37-39

Answer me, O LORD, answer me, that this people may know that You, O LORD, are God, and that You have turned their heart back again.” Then the fire of the LORD fell and consumed the burnt offering and the wood and the stones and the dust, and licked up the water that was in the trench. When all the people saw it, they fell on their faces; and they said, “The LORD, He is God; the LORD, He is God.”
