Genesis 27:30-33

Now it came about, as soon as Isaac had finished blessing Jacob, and Jacob had hardly gone out from the presence of Isaac his father, that Esau his brother came in from his hunting. Then he also made savory food, and brought it to his father; and he said to his father, “Let my father arise and eat of his son’s game, that you may bless me.” Isaac his father said to him, “Who are you?” And he said, “I am your son, your firstborn, Esau.” Then Isaac trembled violently, and said, “Who was he then that hunted game and brought it to me, so that I ate of all of it before you came, and blessed him? Yes, and he shall be blessed.”
