1 Kings 18:23-24

23Get two bulls for us. Let Baal’s prophets choose one for themselves, and let them cut it into pieces and put it on the wood but not set fire to it. I will prepare the other bull and put it on the wood but not set fire to it.

24Then you call on the name of your god, and I will call on the name of the LORD . The god who answers by fire—he is God.” Then all the people said, “What you say is good.”
