E‧sau /ˈiːsɔː/
in the Old Testament of the Bible, the son of Isaac, and the older brother of Jacob, whose twin (=one of two children born at the same time) he was. Esau was very hungry and so he sold his birthright (=the property or possessions that he had a right to receive from his parents) to Jacob for ‘a mess of pottage’, that is for some soup that Jacob had made.
