Genesis 27:19-24

Jacob said to his father, “I am Esau your firstborn; I have done as you told me. Get up, please, sit and eat of my game, that you may bless me.” Isaac said to his son, “How is it that you have it so quickly, my son?” And he said, “Because the LORD your God caused it to happen to me.” 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. And he said, “Are you really my son Esau?” And he said, “I am.”
