1 Kings 18:15-24

But Elijah said, “I swear by the LORD Almighty, in whose presence I stand, that I will present myself to Ahab this very day.” So Obadiah went to tell Ahab that Elijah had come, and Ahab went out to meet Elijah. When Ahab saw him, he exclaimed, “So, is it really you, you troublemaker of Israel?” “I have made no trouble for Israel,” Elijah replied. “You and your family are the troublemakers, for you have refused to obey the commands of the LORD and have worshiped the images of Baal instead. Now summon all Israel to join me at Mount Carmel, along with the 450 prophets of Baal and the 400 prophets of Asherah who are supported by Jezebel.” So Ahab summoned all the people of Israel and the prophets to Mount Carmel. Then Elijah stood in front of them and said, “How much longer will you waver, hobbling between two opinions? If the LORD is God, follow him! But if Baal is God, then follow him!” But the people were completely silent. Then Elijah said to them, “I am the only prophet of the LORD who is left, but Baal has 450 prophets. Now bring two bulls. The prophets of Baal may choose whichever one they wish and cut it into pieces and lay it on the wood of their altar, but without setting fire to it. I will prepare the other bull and lay it on the wood on the altar, but not set fire to it. Then call on the name of your god, and I will call on the name of the LORD. The god who answers by setting fire to the wood is the true God!” And all the people agreed.
