Ya`akov said to Rivka his mother, *Behold, Esav my brother is a hairy man, and I am a smooth man.
The first came out red all over, like a hairy garment. They named him Esav.
You shall bring it to your father, that he may eat, so that he may bless you before his death.*
He didn't recognize him, because his hands were hairy, like his brother, Esav's hands. So he blessed him.
