" There are two different stories of the creation of the world. There are two stories of the covenant between God and the patriarch Abraham, two stories of the naming of Abraham’s son Isaac, two stories of Abraham’s claiming to a foreign king that his wife Sarah is his sister, two stories of Isaac’s son Jacob making a journey to Mesopotamia, two stories of a revelation to Jacob at Beth-El, two stories of God’s changing Jacob’s name to Israel, two stories of Moses’ getting water from a rock at a place called Meribah, and more.
