Genesis 27:18-24

18He went to his father and said, “My father.” “Yes, my son,” he answered. “Who is it?”

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 give me your blessing.”

20Isaac asked his son, “How did you find it so quickly, my son?” “The LORD your God gave me success,” he replied.

21Then Isaac said to Jacob, “Come near so I can touch you, my son, to know whether you really are my son Esau or not.” 22Jacob went 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.” 23He did not recognize him, for his hands were hairy like those of his brother Esau; so he proceeded to bless him.

24“Are you really my son Esau?” he asked. “I am,” he replied.
