And it came to pass, as if it was a light thing for him to walk in the sins of Jeroboam the son of Nebat, that he took as wife Jezebel the daughter of Ethbaal king of the Zidonians; and he went and served Baal and worshipped him.

And he reared up an altar for Baal in the house of Baal, which he built in Samaria.

And he said, I have not troubled Israel, but thou and thy father's house, in that ye have forsaken the commandments of Jehovah, and thou hast followed the Baals.

And now send, gather to me all Israel to mount Carmel, and the prophets of Baal four hundred and fifty, and the prophets of the Asherah four hundred, who eat at Jezebel's table.

Then Elijah drew near to all the people, and said, How long do ye halt between two opinions? if Jehovah be God, follow him; and if Baal, follow him. And the people answered him not a word.

And Elijah said to the people, I, only I, remain a prophet of Jehovah; and Baal's prophets are four hundred and fifty men.

And Elijah said to the prophets of Baal, Choose one bullock for yourselves, and sacrifice it first; for ye are the many; and call on the name of your god, but put no fire.

And they took the bullock which had been given them, and sacrificed it, and called on the name of Baal from morning until noon, saying, O Baal, answer us! But there was no voice, and none answered. And they leaped about the altar that had been made.

So the prophets of Baal cried even louder and slashed themselves with swords and lances until their blood gushed out all over them, as was their custom.

And Elijah said to them, Seize the prophets of Baal; let not one of them escape! And they seized them; and Elijah brought them down to the torrent of Kishon, and slaughtered them there.

Ahab complained to Jezebel about everything that Elijah had done, especially the part about him killing all the prophets of Baal with a sword.

Yet will I leave seven thousand in Israel, all the knees which have not bowed to Baal, and every mouth which has not kissed him."

He served Baal, and worshiped him, and provoked to anger Yahweh, the God of Israel, according to all that his father had done.
