'Ceremonially' in the Bible

“However, you may slaughter and eat meat within any of your [city] gates, whatever you wish, according to the blessing of the Lord your God which He has given you [as His generous provision for daily life]. The [ceremonially] unclean and the clean may eat it, such as the gazelle and the deer.

You shall eat it within your [city] gates; the [ceremonially] unclean and the clean alike may eat it, as [if it were] a gazelle or a deer.

I have not eaten anything when I was in mourning, or removed any of it while ceremonially unclean, or offered any of it to the dead; I have obeyed you and have done everything you have commanded me.
