Then said Elijah unto the people, I, even I only remain a prophet of the Lord; but Baal's prophets are four hundred and fifty men
Let them therefore give us two bullocks; and let them choose one bullock for themselves, and cut it in pieces, and lay it on wood, and put no fire under: and i will dress the other bullock, and lay it on wood, and put no fire under. 1 Kings 18:22-23

And call ye on the name of your gods, and I will call on the name of the Lord: and the God that answered by fire, let him be God. And all the people answered and said, It is well spoken. 1 Kings 24

And they took the bullock which was given them, and they dressed it, and called on the name of Baal from morning even until noon, saying, O Baal, hear us. But there was no voice, not any that answered. And they leaped upon the altar which was made.
And it came to pass at noon, that Elijah mocked them, and said, Cry aloud: for he is a god; either he is talking, or he is pursuing, or he is in a journey, or peradventure he sleepeth and must be awaked.
1 Kings 18:26-27

And he put the wood in order, and cut the bullock in pieces, and laid him on the wood, and said, Fill four barrels with water, and pour it on the burnt sacrifice, and on the wood.
And he said, Do it the second time. And they did it the second time. And he said, Do it a third time. And they did it the third time.
1 Kings 18:33-34

Hear me, O LORD, hear me, that this people may know that thou art the LORD God, and that thou hast turned their heart back again.
Then the fire of the LORD fell and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench.
1 Kings 18:37-38
