He did not recognize him because his hands were hairy, like his brother Esau’s hands. So Isaac blessed Jacob.
“But Esau my brother is a hairy man,” Jacob protested to his mother Rebekah, “and I have smooth skin!
She put the skins of the young goats on his hands and the smooth part of his neck.
So Jacob went over to his father Isaac, who felt him and said, “The voice is Jacob’s, but the hands are Esau’s.”
Then he asked, “Are you really my son Esau?” “I am,” Jacob replied.
By faith also Isaac blessed Jacob and Esau concerning the future.
