Jacob said to his mother Rebekah, “My brother Esau is a hairy man, and my skin is smooth.
The first one born was red. His whole body was covered with hair, so they named him Esau [Hairy].
Then take it to your father to eat so that he will bless you before he dies.”
He didn’t recognize Jacob, because his hands were hairy like his brother Esau’s hands. So he blessed him.
