1 Kings 18:30-41

Then Elijah said to all the people, “Come near to me.” So all the people approached him. And he repaired and rebuilt the [old] altar of the LORD that had been torn down [by Jezebel]. [1 Kin 18:13; 19:10] Then Elijah took twelve stones in accordance with the number of the tribes of the sons of Jacob, to whom the word of the LORD had come, saying, “Israel shall be your name.” [Gen 32:28] So with the stones Elijah built an altar in the name of the LORD. He made a trench around the altar large enough to hold two measures of seed. Then he laid out the wood and cut the ox in pieces and laid it on the wood. And he said, “Fill four pitchers with water and pour it on the burnt offering and the wood.” And he said, “Do it the second time.” And they did it the second time. And he said, “Do it the third time.” And they did it a third time. The water flowed around the altar, and he also filled the trench with water. At the time of the offering of the evening sacrifice, Elijah the prophet approached [the altar] and said, “O LORD, the God of Abraham, Isaac, and Israel (Jacob), let it be known today that You are God in Israel and that I am Your servant and that I have done all these things at Your word. Answer me, O LORD, answer me, so that this people may know that You, O LORD, are God, and that You have turned their hearts back [to You].” Then the fire of the LORD fell and consumed the burnt offering and the wood, and even the stones and the dust; it also licked up the water in the trench. When all the people saw it, they fell face downward; and they said, “The LORD, He is God! The LORD, He is God!” Then Elijah said to them, “Seize the prophets of Baal; do not let one of them escape.” They seized them; and Elijah brought them down to the brook Kishon, and [as God’s law required] killed them there. [Deut 13:5, 12-15; 18:20] Now Elijah said to Ahab, “Go up, eat and drink, for there is the sound of the roar of an abundance of rain.”
