Genesis 27:17-21

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

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

And Jacob said unto his father, I am Esau thy firstborn; 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.
