1 Kings 18:25-26, 28-29

Elijah said to the prophets of Baal, “Choose one bull for yourselves and prepare it first, since there are many of you; and call on the name of your god, but put no fire under it.” So they took the bull that was given to them and prepared it, and called on the name of Baal from morning until noon, saying, “O Baal, hear and answer us.” But there was no voice and no one answered. And they leaped about the altar which they had made.

So they cried out with a loud voice [to get Baal’s attention] and cut themselves with swords and lances in accordance with their custom, until the blood flowed out on them. As midday passed, they played the part of prophets and raved dramatically until the time for offering the evening sacrifice; but there was no voice, no one answered, and no one paid attention.
