The mention of the prophets of Baal is a reference to the biblical story of Elijah found in the Bible in 1 Kings 18. The story of Elijah goes as follows: the prophet Elijah challenged 450 prophets of Baal and 400 prophets of Asherah to a contest. He asked them to prove that their God, Baal, was truly powerful. They were both to make an altar and place a bull on the alter without lighting it. The prophets of Baal were to make their sacrifice to their god and Elijah to his. The lighting of the fire was to be left to the strongest God. Baal was silent and Elijah mocked the prophets. Then he poured water on his own alter and the fire of the Lord fell and consumed the sacrifice. Elijah commanded his people to seize the prophets of Baal and they were executed.
