1 Kings 18:23-24

Let 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. And 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.
