Jacob's Biblical brother is Esau, who is mentioned in the Hebrew Bible. He was the twin brother of Jacob and the older son of Isaac and Rebekah. Esau was a hunter and outdoorsman, while Jacob was a quiet man who stayed at home. Esau sold his birthright to Jacob for a bowl of stew, and later Jacob tricked their father into giving him the blessing that was meant for Esau. This caused a rift between the two brothers, and they eventually reconciled.
