chunk: God tests Abraham by demanding that he sacrifice Isaac. As Abraham is about to lay the knife upon his son, God restrains him, promising him numberless descendants. On the death of Sarah, Abraham purchases Machpelah (believed to be modern Hebron) for a family tomb and sends his servant to Mesopotamia to find among his relations a wife for Isaac, and Rebekah is chosen. Other children are born to Abraham by another wife, Keturah, among whose descendants are the Midianites, and he dies in a prosperous old age and is buried in his tomb at Hebron.
  Isaac's wife Rebecca gives birth to the twins Esau, father of the Edomites, and Jacob. Through deception, Jacob becomes the heir instead of Esau and gains his father's blessing. He flees to his uncle where he prospers and earns his two wives, Rachel and Leah. Jacob's name is changed to Israel, and by his wives and their handmaidens he has twelve sons, the ancestors of the twelve tribes of the Children of Israel, and a daughter, Dinah.
