In the third year of the drought, the famine is severe in Samaria. Ahab calls Obadiah, the manager of his household, who feared the Lord greatly and had hidden a hundred prophets from Jezebel, and together they travel the land looking for grass. Elijah meets Obadiah and asks him to tell Ahab. Obadiah fears for his life, but Elijah swears that he will present himself. When Ahab sees him, he calls him the troubler of Israel, and Elijah answers that the troubler is Ahab, for abandoning the Lord's commands and following the Baals.
Elijah orders all Israel and the four hundred fifty prophets of Baal gathered on Mount Carmel. He asks the people how long they will waver between two opinions: if the Lord is God, follow him; if Baal, follow him. He proposes that each side prepare a bull and place it on wood without lighting a fire, and that the god who answers with fire be recognized as God. The prophets of Baal call from morning until noon and cut themselves, with no answer; Elijah mocks them.
At the time of the offering, Elijah repairs the altar of the Lord with twelve stones, digs a trench, places the bull on the wood and has everything drenched with water three times. He prays briefly that it be known the Lord is God in Israel. Fire from the Lord falls and consumes the burnt offering, the wood, the stones and the water. The people fall on their faces and say the Lord is God. Elijah has the prophets of Baal killed at the brook Kishon.
Elijah tells Ahab to go up and eat and drink, because there is the sound of heavy rain. Elijah climbs to the top of Carmel, bows down and prays seven times. At the seventh, his servant sees a little cloud like a man's hand. Elijah sends word to Ahab to hurry. Soon the sky grows black, heavy rain comes, Ahab rides in his chariot, and the hand of the Lord is on Elijah, who runs ahead of the chariot to Jezreel.
