Genesis 27:12, 19, 35

If my father touches me, he will know I am not Esau. Then he will not bless me but will place a curse on me because I tried to trick him.”

Jacob said to him, “I am Esau, your first son. I have done what you told me. Now sit up and eat some meat of the animal I hunted for you. Then bless me.”

But Isaac said, “Your brother came and tricked me. He has taken your blessing.”
