1 Kings 18:19-24

19Now therefore send, and gather to me all Israel unto mount Carmel, and the prophets of Baal four hundred and fifty, and the prophets of the Asherah four hundred, that eat at Jezebel’s table.

20So Ahab sent unto all the children of Israel, and gathered the prophets together unto mount Carmel. 21And Elijah came near unto all the people, and said, How long go ye limping between the two sides? if Jehovah be God, follow him; but if Baal, then follow him. And the people answered him not a word. 22Then said Elijah unto the people, I, even I only, am left a prophet of Jehovah; but Baal’s prophets are four hundred and fifty men. 23Let them therefore give us two bullocks; and let them choose one bullock for themselves, and cut it in pieces, and lay it on the wood, and put no fire under; and I will dress the other bullock, and lay it on the wood, and put no fire under. 24And call ye on the name of your god, and I will call on the name of Jehovah; and the God that answereth by fire, let him be God. And all the people answered and said, It is well spoken.
