Elijah, Baal

This catastrophe will come because Ahab and his queen--Jezebel--stand at the end of a line of kings of Israel who are said to have "done evil in the sight of the Lord." In particular, Ahab and Jezebel had encouraged the worship of Baal and killed the prophets of the Lord.

Two altars are built, one for Baal and one for the God of Israel. Wood is laid on the altars. Two oxen are slaughtered and cut into pieces; the pieces are laid on the wood. Elijah then invites the priests of Baal to pray for fire to light the sacrifice. They pray from morning to noon without success. Elijah ridicules their efforts. They respond by cutting themselves and adding their own blood to the sacrifice. They continue praying until evening without success.

The first stage dates from the final edition of the History, about 560 BCE, when the three stories of Naboths vineyard, the death of Ahaziah, and the story of Jehus coup were included to embody the themes of the reliability of God's word and the cycle of Baal worship and religious reform in the history of the Northern Kingdom. The narratives about the Omride wars were added shortly afterwards to illustrate a newly-introduced theme, that the attitude of the king towards the word of the prophets determines the fate of Israel.
