1 Kings 18:20-24

So Ahab sent a message among all the sons of Israel and brought the prophets together at Mount Carmel. Elijah came near to all the people and said, “How long will you hesitate between two opinions? If the LORD is God, follow Him; but if Baal, follow him.” But the people did not answer him a word. Then Elijah said to the people, “I alone am left a prophet of the LORD, but Baal’s prophets are 450 men. Now let them give us two oxen; and let them choose one ox for themselves and cut it up, and place it on the wood, but put no fire under it; and I will prepare the other ox and lay it on the wood, and I will not put a fire under it. Then you call on the name of your god, and I will call on the name of the LORD, and the God who answers by fire, He is God.” And all the people said, “That is a good idea.”
