Genesis 27:19-24

19Jacob said to his father, “I am Esau, your firstborn. I have done as you told me. Please sit up and eat some of my game, so that you may bless me.”

20But Isaac asked his son, “How did you ever find it so quickly, my son?”

“Because the LORD your God brought it to me,” he replied.

21Then Isaac said to Jacob, “Please come closer so I can touch you, my son. Are you really my son Esau, or not?”

22So Jacob came close to his father Isaac, who touched him and said, “The voice is the voice of Jacob, but the hands are the hands of Esau.” 23Isaac did not recognize him, because his hands were hairy like those of his brother Esau; so he blessed him.

24Again he asked, “Are you really my son Esau?”

And he replied, “I am.”
