Genesis 27:19-24

Jacob 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.” Isaac asked his son, “How did you find it so quickly, my son?” “The LORD your God gave me success,” he replied. Then Isaac said to Jacob, “Come near so I can touch you, my son, to know whether you really are my son Esau or not.” Jacob 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.” He did not recognize him, for his hands were hairy like those of his brother Esau; so he proceeded to bless him. “Are you really my son Esau?” he asked. “I am,” he replied.
