Isaac did not know it was Jacob, because his hands were hairy like Esau’s hands, so Isaac blessed him.
But Jacob said to his mother Rebekah, “My brother Esau is a hairy man, and I am smooth!
She also took the skins of the goats and put them on Jacob’s hands and neck.
So Jacob came near to Isaac his father. Isaac touched him and said, “Your voice sounds like Jacob’s voice, but your hands are hairy like the hands of Esau.”
Isaac asked, “Are you really my son Esau?” Jacob answered, “Yes, I am.”
It was by faith that Isaac blessed the future of Jacob and Esau.
