Genesis 27:20-24

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.”

And 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.”
