'Unclean' in the Bible

“However, you may slaughter and eat meat within any of your gates, whatever you desire, according to the blessing of the Lord your God which He has given you; the unclean and the clean may eat of it, as of the gazelle and the deer.

Just as a gazelle or a deer is eaten, so you will eat it; the unclean and the clean alike may eat of it.

Nevertheless, you are not to eat of these among those which chew the cud, or among those that divide the hoof in two: the camel and the rabbit and the shaphan, for though they chew the cud, they do not divide the hoof; they are unclean for you.

The pig, because it divides the hoof but does not chew the cud, it is unclean for you. You shall not eat any of their flesh nor touch their carcasses.

but anything that does not have fins and scales you shall not eat; it is unclean for you.

And all the teeming life with wings are unclean to you; they shall not be eaten.

You shall eat it within your gates; the unclean and the clean alike may eat it, as a gazelle or a deer.

“If there is among you any man who is unclean because of a nocturnal emission, then he must go outside the camp; he may not reenter the camp.

I have not eaten of it while mourning, nor have I removed any of it while I was unclean, nor offered any of it to the dead. I have listened to the voice of the Lord my God; I have done according to all that You have commanded me.
