Genesis 27:23 (KJV)

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.

And he said, Art thou my very son Esau? And he said, I am.

And he said, Bring it near to me, and I will eat of my son’s venison, that my soul may bless thee. And he brought it near to him, and he did eat: and he brought him wine, and he drank.
