And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me: therefore suffered I thee not to touch her.

My father might touch me and he'll realize that I'm deceiving him. Then, I'll bring a curse on myself instead of a blessing."

Then Isaac said to Jacob, “Please come closer so I can touch you, my son. Are you really my son Esau or not?”
