Genesis 27:18-23

18And he came to his father, and said, My father! And he said, Here am I: who art thou, my son?

19And Jacob said to his father, I am Esau, thy firstborn. I have done according as thou didst say to me. Arise, I pray thee, sit and eat of my venison, in order that thy soul may bless me.

20And Isaac said to his son, How is it that thou hast found [it] so quickly, my son? And he said, Because Jehovah thy 1God put [it] in my way.

21And Isaac said to Jacob, Come near, I pray thee, that I may feel thee, my son, whether thou be really my son Esau or not.

22And Jacob drew near to Isaac his father; and he felt him, and said, The voice is Jacob's voice, but the hands are the hands of Esau.

23And he did not discern him, because his hands were hairy, as his brother Esau's hands; and he blessed him.
