Genesis 27:19-23
27:19 Jacob said to his father, “I am Esau, your firstborn. I’ve done as you told me. Now sit up and eat some of my wild game so that you can bless me.”
27:20 But Isaac asked his son, “How in the world did you find it so quickly, my son?” “Because the Lord your God brought it to me,” he replied.
27:21 Then Isaac said to Jacob, “Come closer so I can touch you, my son, and know for certain if you really are my son Esau.”
27:22 So Jacob went over to his father Isaac, who felt him and said, “The voice is Jacob’s, but the hands are Esau’s.”
27:23 He did not recognize him because his hands were hairy, like his brother Esau’s hands. So Isaac blessed Jacob.
