These are the descendants of Isaac, Abraham's son: Abraham was the father of Isaac, and Isaac was forty years old when he took to wife Rebekah, the daughter of Bethu'el the Aramean of Paddan-aram, the sister of Laban the Aramean. And Isaac prayed to the LORD for his wife, because she was barren; and the LORD granted his prayer, and Rebekah his wife conceived. The children struggled together within her; and she said, "If it is thus, why do I live?" So she went to inquire of the LORD. And the LORD said to her, "Two nations are in your womb, and two peoples, born of you, shall be divided; the one shall be stronger than the other, the elder shall serve the younger." When her days to be delivered were fulfilled, behold, there were twins in her womb.
The first came forth red, all his body like a hairy mantle; so they called his name Esau. Afterward his brother came forth, and his hand had taken hold of Esau's heel; so his name was called Jacob. Isaac was sixty years old when she bore them. When the boys grew up, Esau was a skilful hunter, a man of the field, while Jacob was a quiet man, dwelling in tents. Isaac loved Esau, because he ate of his game; but Rebekah loved Jacob.
Once when Jacob was boiling pottage, Esau came in from the field, and he was famished. And Esau said to Jacob, "Let me eat some of that red pottage, for I am famished!" (Therefore his name was called Edom.) Jacob said, "First sell me your birthright." Esau said, "I am about to die; of what use is a birthright to me?" Jacob said, "Swear to me first." So he swore to him, and sold his birthright to Jacob. Then Jacob gave Esau bread and pottage of lentils, and he ate and drank, and rose and went his way. Thus Esau despised his birthright.
