Genesis 27:19

17And she gave the savoury meat and the bread, which she had prepared, into the hand of her son Jacob.

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

19And 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.

20And 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.

21And 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.
