Genesis 27:1-4; Genesis 27:22-23
Now when Isaac was old and his eyes had become clouded so that he was not able to see, he sent for Esau, his first son, and said to him, My son: and he said, Here am I.
And he said, See now, I am old, and my death may take place at any time:
So take your arrows and your bow and go out to the field and get meat for me;
And make me food, good to the taste, such as is pleasing to me, and put it before me, so that I may have a meal and give you my blessing before death comes to me.
And Jacob went near his father Isaac: and he put his hands on him; and he said, The voice is Jacob's voice, but the hands are the hands of Esau.
And he did not make out who he was, because his hands were covered with hair like his brother Esau's hands: so he gave him a blessing.
