'Touch' in the Bible

but concerning the fruit of the tree that is in the middle of the orchard God said, 'You must not eat from it, and you must not touch it, or else you will die.'"

Then in the dream God replied to him, "Yes, I know that you have done this with a clear conscience. That is why I have kept you from sinning against me and why I did not allow you to touch her.

My father may touch me! Then he'll think I'm mocking him and I'll bring a curse on myself instead of a blessing."

Then Isaac said to Jacob, "Come closer so I can touch you, my son, and know for certain if you really are my son Esau."
