Genesis 27:30-33

Now it happened, as soon as Isaac had finished blessing Jacob, and Jacob had scarcely gone out from the presence of Isaac his father, that Esau his brother came in from his hunting. He also had made savory food, and brought it to his father, and said to his father, “Let my father arise and eat of his son’s game, that your soul may bless me.” And his father Isaac said to him, “Who are you?” So he said, “I am your son, your firstborn, Esau.” Then Isaac trembled exceedingly, and said, “Who? Where is the one who hunted game and brought it to me? I ate all of it before you came, and I have blessed him—and indeed he shall be blessed.”
