Genesis 27:30-35

As soon as Isaac had finished blessing Jacob, and almost before Jacob had left his father, Esau returned from his hunt. Esau prepared a delicious meal and brought it to his father. Then he said, “Sit up, my father, and eat my wild game so you can give me your blessing.” But Isaac asked him, “Who are you?” Esau replied, “It’s your son, your firstborn son, Esau.” Isaac began to tremble uncontrollably and said, “Then who just served me wild game? I have already eaten it, and I blessed him just before you came. And yes, that blessing must stand!” When Esau heard his father’s words, he let out a loud and bitter cry. “Oh my father, what about me? Bless me, too!” he begged. But Isaac said, “Your brother was here, and he tricked me. He has taken away your blessing.”
