Genesis 27:19-24

Jacob said to his father, “I am Esau your firstborn; I have done what you told me to do. Now please, sit up and eat some of my game, so that you may bless me.” Isaac said to his son, “How is it that you have found the game so quickly, my son?” And he said, “Because the LORD your God caused it to come to me.” But Isaac [wondered and] said to Jacob, “Please come close [to me] so that I may touch you, my son, and determine if you are really my son Esau or not.” So Jacob approached Isaac, and his father touched him and said, “The voice is Jacob’s voice, but the hands are the hands of Esau.” He could not recognize him [as Jacob], because his hands were hairy like his brother Esau’s hands; so he blessed him. But he said, “Are you really my son Esau?” Jacob answered, “I am.”
