Genesis 27:20-22

But Isaac said to his son, “How is it that you have found it so quickly, my son?” He answered, “Because the LORD your God granted me success.” Then Isaac said to Jacob, “Please come near, that I may feel you, my son, to know whether you are really my son Esau or not.” So Jacob went near to Isaac his father, who felt him and said, “The voice is Jacob’s voice, but the hands are the hands of Esau.”
