1 Kings 18:37-39

37Answer me, O Lord, answer me, that this people may know that you, O Lord, are God, and that you have turned their hearts back."

38Then 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.

39And when all the people saw it, they fell on their faces and said, "The Lord, he is God; the Lord, he is God."
