'Ceremonially' in the Bible

The Lord said, “This is how the Israelites will eat their bread—ceremonially unclean—among the nations where I will banish them.”

And I said, "Ah, sovereign Lord, I have never been ceremonially defiled before. I have never eaten a carcass or an animal torn by wild beasts; from my youth up, unclean meat has never entered my mouth."

In you men have uncovered their fathers’ nakedness [the nakedness of mother or stepmother]; in you they have violated women who are [set apart as ceremonially] unclean during their menstrual impurity [or after childbirth].

Moreover, they will teach my people the difference between the holy and the common, and show them how to distinguish between the ceremonially unclean and the clean.

After a priest has become ceremonially clean, they must count off a period of seven days for him.
