'Unclean' 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.

Just as the gazelle or the deer is eaten, so you may eat it [but not make it an offering]; the [ceremonially] unclean and the clean alike may eat it.

However, you are not to eat any of these [animals] among those which chew the cud, or among those that divide the hoof in two: the camel, the hare and the shaphan, for though they chew the cud, they do not split the hoof; they are unclean for you.

The swine, because it has a divided hoof but does not chew the cud; it is unclean for you. You shall not eat their meat nor touch their carcasses.

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

And all flying insects are unclean for you; they shall not be eaten.

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.

“You shall not plow with an ox [a clean animal] and a donkey [an unclean animal] together.

I have not eaten from the tithe while mourning, nor have I removed any of it when I was [ceremonially] unclean [making the tithe ceremonially unclean], nor offered any of it to the dead. I have listened to the voice of the Lord my God; I have done everything in accordance with all that You have commanded me.
