'Contact' in the Bible

“Command the Israelites to send away from the camp every leper and everyone who has a discharge, and whoever is defiled [that is, ceremonially unclean] by [coming in contact with] the dead.

So the Lord said to Aaron, “You and your sons and your father’s household (family) with you shall bear the guilt in connection with the sanctuary [that is, through your service as priests you will atone for the offenses which the people unknowingly commit when brought into contact with the manifestations of God’s presence]; and you and your sons with you shall bear the guilt in connection with your priesthood [that is, your own unintentional offenses].
