Genesis 27:12, 19, 35

Suppose my father touches me and feels my skin; then I will be seen by him as a cheat (imposter), and I will bring his curse on me and not a blessing.”

Jacob said to his father, “I am Esau your firstborn; I have done what you told me to do. Now please, sit up and eat some of my game, so that you may bless me.”

Isaac said, “Your brother came deceitfully and has [fraudulently] taken away your blessing [for himself].”
