Kings III 18:24

24 And do ye call loudly on the name of your gods, and I will call on the name of the Lord my God, and it shall come to pass that the God who shall answer by fire, he God. And all the people answered and said, The word which thou hast spoken good.

Kings III 18:24 In-Context

22 And Eliu said to the people, I am left, the only one prophet of the Lord; and the prophets of Baal four hundred and fifty men, and the prophets of the groves four hundred.
23 Let them give us two oxen, and let them choose one for themselves, and cut it in pieces, and lay it on the wood, and put no fire the wood: and I will dress the other bullock, and put on no fire.
24 And do ye call loudly on the name of your gods, and I will call on the name of the Lord my God, and it shall come to pass that the God who shall answer by fire, he God. And all the people answered and said, The word which thou hast spoken good.
25 And Eliu said to the prophets of shame, Choose to yourselves one calf, and dress it first, for ye many; and call ye on the name of your god; but apply no fire.
26 And they took the calf and drest it, and called on the name of Baal from morning till noon, and said, hear us, O Baal, hear us. And there was no voice, neither was there hearing, and they ran up and down on the alter which they made.
