'Contact' in the Bible

‘The meat that comes in contact with anything that is unclean shall not be eaten; it shall be burned in the fire. As for other meat, everyone who is [ceremonially] clean may eat it.

‘By [contact with] these you will become unclean; whoever touches their carcasses becomes unclean until the evening (dusk),

No man of the descendants of Aaron who is a leper or has a discharge may eat the holy things [the offerings and the showbread] until he is clean. And whoever touches any person or thing made unclean by contact with a corpse or a man who has had a seminal emission,

“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].

When they go out into the outer court, into the outer courtyard to the people, they shall take off the garments in which they have been ministering and leave them in the holy chambers; then they shall put on other clothing so that they will not transmit holiness to the people with their [ceremonial] garments.

Then Haggai said, “If one who is [ceremonially] unclean because of [contact with] a corpse touches any of these [articles of food], will it be unclean?” And the priests answered, “It will be unclean.” [Ceremonial uncleanness, like sin, is infectious.]

Therefore, if anyone cleanses himself from these things [which are dishonorable—disobedient, sinful], he will be a vessel for honor, sanctified [set apart for a special purpose and], useful to the Master, prepared for every good work.
