I Kings 18:17-24
17 And it came to pass, when Ahab saw Elijah, that Ahab said unto him, Art thou he that troubleth Israel?

18 And 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.

19 Now 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.

20 So Ahab sent unto all the children of Israel, and gathered the prophets together unto mount Carmel.

21 And 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.

22 Then 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.

23 Let 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:

24 And 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.

1 Kings 18:20-21
(20) So Ahab sent unto all the children of Israel, and gathered the prophets together unto mount Carmel.
(21) And 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.

I Kings 18:1-16
1 And it came to pass after many days, that the word of the LORD came to Elijah in the third year, saying, Go, shew thyself unto Ahab; and I will send rain upon the earth.
2 And Elijah went to shew himself unto Ahab. And there was a sore famine in Samaria.
3 And Ahab called Obadiah, which was the governor of his house. (Now Obadiah feared the LORD greatly:
4 For it was so, when Jezebel cut off the prophets of the LORD, that Obadiah took an hundred prophets, and hid them by fifty in a cave, and fed them with bread and water.)
5 And Ahab said unto Obadiah, Go into the land, unto all fountains of water, and unto all brooks: peradventure we may find grass to save the horses and mules alive, that we lose not all the beasts.
6 So they divided the land between them to pass throughout it: Ahab went one way by himself, and Obadiah went another way by himself.
7 And as Obadiah was in the way, behold, Elijah met him: and he knew him, and fell on his face, and said, Art thou that my lord Elijah?
8 And he answered him, I am: go, tell thy lord, Behold, Elijah is here.
9 And he said, What have I sinned, that thou wouldest deliver thy servant into the hand of Ahab, to slay me?
10 As the LORD thy God liveth, there is no nation or kingdom, whither my lord hath not sent to seek thee: and when they said, He is not there; he took an oath of the kingdom and nation, that they found thee not.
11 And now thou sayest, Go, tell thy lord, Behold, Elijah is here.
12 And it shall come to pass, as soon as I am gone from thee, that the Spirit of the LORD shall carry thee whither I know not; and so when I come and tell Ahab, and he cannot find thee, he shall slay me: but I thy servant fear the LORD from my youth.
13 Was it not told my lord what I did when Jezebel slew the prophets of the LORD, how I hid an hundred men of the LORD'S prophets by fifty in a cave, and fed them with bread and water?
14 And now thou sayest, Go, tell thy lord, Behold, Elijah is here: and he shall slay me.
15 And Elijah said, As the LORD of hosts liveth, before whom I stand, I will surely shew myself unto him to day.
16 So Obadiah went to meet Ahab, and told him: and Ahab went to meet Elijah.
