Jacob and Esau were twin son of of Isaac and Rebeckah.
Isaac's family had a problem similar to that of Abraham and Sarah. Rebekah was barren. But Isaac did not even consider taking a concubine. He simply prayed and waited on God. God blessed Rebekah's prayerful faith. The Lord said to her, 'Two nations are in your womb, and two peoples from within you will be separated; one people will be stronger than the other, and the older will serve the younger.'" and blessed her with twin boys Jacob and Esau.
Both were as different as day and night. First, they were different in appearance: Jacob was smooth and Esau was red and hairy. Second, they were different in character: Esau was a sportsman. He liked to hunt and fish and play around with women; Jacob was a quiet man who liked to stay at home and hang around his mother in the kitchen.
