“But listen,” Jacob replied to his mother Rebekah, “my brother Esau is a hairy man, and I'm a smooth man.
The first baby to be born was red, and covered with hair like a coat. So they named him Esau.
Then you take it to your father to eat, so he can bless you in the presence of the Lord before he dies.”
Isaac didn't realize it was really Jacob because his hands were hairy like his brother Esau's, so Isaac got ready to bless him.
