Now Isaac had came from The field one evening to meditate, and he looked up, he saw camels approaching. Rebekah also looked up and saw Isaac. She got down from her camel and asked the servant, "Who is that man in the field coming to meet us?" He is my master the servant answered. So she took her veil and covered her self. Then the servant told Isaac all he had done. Isaac brought her into the tent of his mother Sarah, and he married Rebekah. She became his wife and he loved her; and Isaac was comforted after his mother death. And Isaac was Forty years old when he married Rebekah. Isaac prayed to the Lord on behalf of his wife, because she was barren. The Lord answered his prayer and his wife Rebekah became pregnant. The babies jostled each other within her and she said, “Why this is happening to me?” So she went to inquire of the Lord. The Lord said to her, "Two nations are in your womb an two peoples from within you will be separated; one people will be stronger than the other, and the older will serve the younger." When the time came for her to give birth, there were twin boys in her womb. The first to come out was red and his hole body was like a hairy garment; so they named him Esau. After this, his brother came out, with his hand grasping Esau heel; so he was named Jacob. Isaac was sixty years old when Rebekah gave birth to them.
