I Kings 18 ...
17And it came to pass, when Ahab saw Elijah, that Ahab said unto him, Art thou he that troubleth Israel?
18And he answered, I have not troubled Israel; but thou, and thy father’s house, in that ye have forsaken the commandments of the LORD, and thou hast followed Baalim.
19Now therefore send, and gather to me all Israel unto mount Carmel, and the prophets of Baal four hundred and fifty, and the prophets of the groves four hundred, which eat at Jezebel’s table. 20So Ahab sent unto all the children of Israel, and gathered the prophets together unto mount Carmel.
21And Elijah came unto all the people, and said, How long halt ye between two opinions? if the LORD be God, follow him: but if Baal, then follow him. And the people answered him not a word.
22Then said Elijah unto the people, I, even I only, remain a prophet of the LORD; but Baal’s prophets are four hundred and fifty men. 23Let them therefore give us two bullocks; and let them choose one bullock for themselves, and cut it in pieces, and lay it on wood, and put no fire under: and I will dress the other bullock, and lay it on wood, and put no fire under: 24And call ye on the name of your gods, and I will call on the name of the LORD: and the God that answereth by fire, let him be God.
And all the people answered and said, It is well spoken.
25And Elijah said unto the prophets of Baal, Choose you one bullock for yourselves, and dress it first; for ye are many; and call on the name of your gods, but put no fire under.
26And they took the bullock which was given them, and they dressed it, and called on the name of Baal from morning even until noon, saying, O Baal, hear us. But there was no voice, nor any that answered. And they leaped upon the altar which was made.
27And it came to pass at noon, that Elijah mocked them, and said, Cry aloud: for he is a god; either he is talking, or he is pursuing, or he is in a journey, or peradventure he sleepeth, and must be awaked.
28And they cried aloud, and cut themselves after their manner with knives and lancets, till the blood gushed out upon them. 29And it came to pass, when midday was past, and they prophesied until the time of the offering of the evening sacrifice, that there was neither voice, nor any to answer, nor any that regarded.
30And Elijah said unto all the people, Come near unto me. And all the people came near unto him. And he repaired the altar of the LORD that was broken down. 31And Elijah took twelve stones, according to the number of the tribes of the sons of Jacob, unto whom the word of the LORD came, saying, Israel shall be thy name: 32And with the stones he built an altar in the name of the LORD: and he made a trench about the altar, as great as would contain two measures of seed. 33And he put the wood in order, and cut the bullock in pieces, and laid him on the wood, and said, Fill four barrels with water, and pour it on the burnt sacrifice, and on the wood. 34And 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 the third time. 35And the water ran round about the altar; and he filled the trench also with water.
36And it came to pass at the time of the offering of the evening sacrifice, that Elijah the prophet came near, and said, LORD God of Abraham, Isaac, and of Israel, let it be known this day that thou art God in Israel, and that I am thy servant, and that I have done all these things at thy word. 37Hear me, O LORD, hear me, that this people may know that thou art the LORD God, and that thou hast turned their heart back again.
38Then the fire of the LORD fell, and consumed the burnt sacrifice, and the wood, and the stones, and the dust, and licked up the water that was in the trench. 39And when all the people saw it, they fell on their faces: and they said, The LORD, he is the God; the LORD, he is the God.\
40And Elijah said unto them, Take the prophets of Baal; let not one of them escape. And they took them:
and Elijah brought them down to the brook Kishon, and slew them there.
I Kings 19 ...
1And Ahab told Jezebel all that Elijah had done, and withal how he had slain all the prophets with the sword.
2Then Jezebel sent a messenger unto Elijah, saying, So let the gods do to me, and more also, if I make not thy life as the life of one of them by to morrow about this time.
(Elijah fled from Jezebel. God restored Elijah. Then Elijah delivered message to Ahab concerning himself and his wife Jezebel)
I Kings 21 ...
17And the word of the LORD came to Elijah the Tishbite, saying, 18Arise, go down to meet Ahab king of Israel, which is in Samaria: behold, he is in the vineyard of Naboth, whither he is gone down to possess it. 19And thou shalt speak unto him, saying, Thus saith the LORD, Hast thou killed, and also taken possession? And thou shalt speak unto him, saying, Thus saith the LORD, In the place where dogs licked the blood of Naboth shall dogs lick thy blood, even thine.
20And Ahab said to Elijah, Hast thou found me, O mine enemy?
And he answered, I have found thee: because thou hast sold thyself to work evil in the sight of the LORD. 21Behold, I will bring evil upon thee, and will take away thy posterity, and will cut off from Ahab him that pisseth against the wall, and him that is shut up and left in Israel, 22And will make thine house like the house of Jeroboam the son of Nebat, and like the house of Baasha the son of Ahijah, for the provocation wherewith thou hast provoked me to anger, and made Israel to sin.
23And of Jezebel also spake the LORD, saying, The dogs shall eat Jezebel by the wall of Jezreel.
24Him that dieth of Ahab in the city the dogs shall eat; and him that dieth in the field shall the fowls of the air eat.
25But there was none like unto Ahab, which did sell himself to work wickedness in the sight of the LORD, whom Jezebel his wife stirred up. 26And he did very abominably in following idols, according to all things as did the Amorites, whom the LORD cast out before the children of Israel.
27And it came to pass, when Ahab heard those words, that he rent his clothes, and put sackcloth upon his flesh, and fasted, and lay in sackcloth, and went softly.
28And the word of the LORD came to Elijah the Tishbite, saying, 29Seest thou how Ahab humbleth himself before me? because he humbleth himself before me, I will not bring the evil in his days: but in his son’s days will I bring the evil upon his house.
