Genesis 27:21-23

American Standard Version

²¹ 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. ²² 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. ²³ And he discerned him not, because his hands were hairy, as his brother Esau’s hands: so he blessed him.
