Genesis 27:1-4; Genesis 27:22-23
When Isaac was old and his eyes were so weak that he could no longer see, he called for Esau his older son and said to him, “My son.” “Here I am,” he answered.
Isaac said, “I am now an old man and don’t know the day of my death.
Now then, get your equipment—your quiver and bow—and go out to the open country to hunt some wild game for me.
Prepare me the kind of tasty food I like and bring it to me to eat, so that I may give you my blessing before I die.”
Jacob went close to his father Isaac, who touched him and said, “The voice is the voice of Jacob, but the hands are the hands of Esau.”
He did not recognize him, for his hands were hairy like those of his brother Esau; so he proceeded to bless him.
