Genesis 27:30-33

30After Isaac finished blessing him, and Jacob had scarcely left his father’s presence, his brother Esau came in from hunting.

31He too prepared some tasty food and brought it to his father. Then he said to him, “My father, please sit up and eat some of my game, so that you may give me your blessing.”

32His father Isaac asked him, “Who are you?” “I am your son,” he answered, “your firstborn, Esau.”

33Isaac trembled violently and said, “Who was it, then, that hunted game and brought it to me? I ate it just before you came and I blessed him—and indeed he will be blessed!”
