Then, when all the Israelis and prophets of Baal were summoned, they prepared two altars - one for Elijah, and for the Lord the God of Israel - and one for the priests of Baal. Then Elijah went to the people and said, "How long will you waver between two opinions? If the Lord is God, follow him; but if Baal is God, follow him." but the people did nor say anything, so he continued: "I am the only one of the Lord's prophets left, but Baal has four hundred and fifty prophets. Get two bulls for us. Let them choose one for themselves, and let them cut it into pieces and put it on the wood but not set fire to it. I will prepare the other bull and put it on the wood but not set fire to it. Then you call on the name of your god, and I will call on the name of the Lord. The god who answers by fire--he is the God." (1 Kings 18:20)
The people agreed to this, and they did as Elijah said. Then the priests of Baal all prepared the bull, and called to Baal all morning till noon. "O Baal, answer us!" but the so-called "Baal" made no reply at all - and the prophets grew weary and discouraged. Elijah, however, was pleased, and he teased them (1 King 18:27), "Shout louder! Surely he is a god! Perhaps he is deep in thought, or busy, or traveling. Maybe he is sleeping and must be awakened." So they shouted even louder and slashed themselves with swords and spears wildly, as was their custom, until the blood flowed from their wounds. After midday passed, it was Elijah's turn - and nobody paid attention to the Baal prophets anymore - so he prepared the sacrifice, and ordered (1 Kings 18:33), "Fill four large jars with water and pour it on the offering and on the wood."
(verse 34) And he said, "Do it again." and they did it again, and a third time, as he said.
Then, after there was so much water it ran down the trench, he stepped forward and prayed (1 Kings 18:36 to 37): "O Lord, God of Abraham, Isaac and Israel, let it be known today that you are God in Israel and that I am your servant and have done all these things at your command. Answer me, O Lord, answer me, so these people will know that you, O Lord, are God, and that you are turning their hearts back again."
Then the fire of the Lord fell and burned up the sacrifice, the wood, the stones and the soil, and also licked up the water in the trench. All the people were awed, and they "fell prostrate" and repented. Then they all seized the prophets of Baal, as Elijah had told them to, and slaughtered them at Kishon Valley. And Ahab went off to eat and drink as Elijah told him to. Then, after climbing the mountain of Carmel and asking his servant seven times if he saw anything above the ocean, the servant answered him at the seventh time--"A cloud as small as a man's hand is rising from the sea." And Elijah told his servant to inform Ahab to go home, because a big rainstorm was coming. Ahab rushed into his chariot and raced home, but the "Power of the Lord came upon Elijah and, tucking his cloak into his belt, he ran ahead of Ahab all the way to Jezreel".
After that, Ahab told to Jezebel about what had happened about Elijah and how the prophets of Baal had been killed by the people of Israel. Jezebel got angry, and sent a message to Elijah that "by this time of the day tomorrow" she would make his "life like that of one of them", referring to the prophets of Baal.
Elijah became scared, and ran away to Beersheba in Judah, left his servant there, and went ahead for a day's journey in the desert. Finally, he came to a broom tree, sat down under it and prayed that he might die (1 Kings 19:4). "I have had enough, Lord," he complained unhappily, "Take my life; I am no better than my ancestors." And he lay down and fell asleep. But the Lord sent an angel to wake him up and feed him some water and a cake of bread "baked over hot coals". Elijah ate and drank and lay down again, and the angel came back again and woke him, and gave him more food. Strengthened by that food, Elijah got up and traveled forty days and forty nights until he reached Horeb, the mountain of God. There he went into a cave and spent the night.
And the Lord appeared to him and asked, "What are you doing here, Elijah?"
He replied not the answer to the Lord's question, but instead of how he had "been very zealous for the Lord God Almighty" and how the Israelites were being unfair to him. The Lord told him to go out and stand on the mountain in the presence of the Lord.
Then the Lord sent a great and powerful wind, and an earthquake, a fire, but the Lord was not in neither: and finally he came in a gentle whisper, and Elijah went out, pulling his cloak over his face. The Lord had tried to show him through all those winds and earthquakes and fires that the Lord was not always harsh, but was more gentle. The Lord asked once again, "What are you doing here, Elijah?" but Elijah again ignored the question and complained about how he had been "Zealous for the Lord God Almighty". So the Lord told him to go anoint many new political and religious leaders, and he did. And he took Elisha, for his next prophet and companion.
After Ahab died, Ahaziah was crowned king, and he became ill. So he sent some people to consult Baal-Zebub, the god of Ekron, to see if he would recover. However, God was very angry and told Elijah to prophesy against Ahaziah. So on the way, Elijah went and met the servants, and told them (2 Kings 1:6) as the Lord had instructed him, "Go back to the king who sent you and tell him, 'This is what the Lord says:Is it because there was no God in Israel that you are sending men to consult Baal-Zebub, the god of Ekron? Therefore (Because of this) you will not leave the bed you are lying on. You will certainly (surely) die!'" And the messengers did has he was told. At King Ahaziah's questions, they described Elijah as "a man with a garment of hair and with a leather belt around his waist". Elijah's cloak was probably of sheepskin or camel's hair, like John the Baptist's, and showed a big difference from the other rich, well-dressed people at that time. He was protesting against the selfishness of the king and the upper classes. The king recognized Elijah by that description (because Elijah had met Ahab, his father, many times), and sent a captain and fifty men to get him. Maybe Ahaziah thought, like many people at that time who did not believe in God, that if he killed Elijah or forced him to change the curse, it would not happen.
The captain he sent said to Elijah, who was sitting on the top of a hill, "Man of God, the king says, 'Come down!'" Ahaziah was trying to place Elijah, the prophet, under his, a king's, power. According to Israel's covenant (promise) with God, the king was supposed to be under the power of the word of the Lord spoken by his prophets.
But Elijah did not come down instead said (2 Kings 1:10, NIV) "If I am a man of God, may fire come down from heaven and consume you and your fifty men! Then fire fell from heaven and consumed the captain and his men. With this, Elijah was showing the king that in Israel, a king was only a servant of the real king, God. Later, Jesus's warning to his disciples when they were trying to call fire down to destroy the Samaritans was not to disapprove of what Elijah did, but to show his disciples that the problem between Elijah and the king and the unfaithfulness of the Samaritans was very different.
The king sent to Elijah another captain with his fifty men, and they, too, were burned up by fire. Finally, the king sent a third captain with his fifty men, who "...fell on his knees before Elijah..." and bowed before him, humbly asking him to come. Elijah was told by the angel of the Lord to go down, so he went down and told the king again, "You will certainly die!" "So he died, according to the word of the Lord that Elijah had spoken". (2 Kings 1:17, NIV)
