Genesis 27:18-22

Then he came to his father and said, “My father.” And he said, “Here I am. Who are you, my son?”

Jacob said to his father, “I am Esau your firstborn; I have done as you told me. Come now, sit and eat of my game, so 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 made it come to me.”

Then Isaac said to Jacob, “Please come close, so that I may feel you, my son, whether you are really my son Esau or not.”

So Jacob came close to his father Isaac, and he touched him and said, “The voice is the voice of Jacob, but the hands are the hands of Esau.”
