Elijah, Two Oxen

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.
