And Jacob said unto his father, I am Esau thy first born; I have done according as thou badest me: arise, I pray thee, sit and eat of my venison, that thy soul may bless me.
And Isaac said unto his son, How is it that thou hast found it so quickly, my son? And he said, Because the LORD thy God brought it to me.
And Isaac said unto Jacob, Come near, I pray thee, that I may feel thee, my son, whether thou be my very son Esau or not.
And Jacob went near unto Isaac his father; and he felt him, and said, The voice is Jacob’s voice, but the hands are the hands of Esau.
And he discerned him not, because his hands were hairy, as his brother Esau’s hands: so he blessed him.
