Jacob's brother is Esau, who is mentioned in the Bible. He was the twin brother of Jacob and the son of Isaac and Rebekah. Esau was a skilled hunter and outdoorsman, while Jacob was a quiet man who stayed in tents. Esau was the firstborn son of Isaac and Rebekah, and as such was entitled to the birthright, which included a double portion of the inheritance. However, Jacob tricked Esau out of his birthright by offering him a bowl of stew in exchange for it. This event is seen as a major turning point in the history of the Israelites.
