Genesis 27:21-23

Then Isaac said to Jacob, “Please come close, that I may feel you, my son, whether you are really my son Esau or not.” So Jacob came close to Isaac his father, and he felt him and said, “The voice is the voice of Jacob, but the hands are the hands of Esau.” He did not recognize him, because his hands were hairy like his brother Esau’s hands; so he blessed him.
