'Unclean' in the Bible

Only you may put to death animals, such as the gazelle or the roe, for your food in any of your towns, at the desire of your soul, in keeping with the blessing of the Lord your God which he has given you: the unclean and the clean may take of it.

It will be your food, like the gazelle and the roe; the unclean and the clean may take of it.

But even among these, there are some which may not be used for food: such as the camel, the hare, and the coney, which are unclean to you, because, though their food comes back, the horn of their feet is not parted in two.

And the pig is unclean to you, because though it has a division in the horn of its foot, its food does not come back; their flesh may not be used for food or their dead bodies touched by you.

But any which have no skin-plates or wings for swimming, you may not take; they are unclean for you.

Every winged thing which goes flat on the earth is unclean to you and may not be used as food.

It may be used for food in your houses: the unclean and the clean may take of it, as of the gazelle and the roe.

Do not let his body be on the tree all night, but put it to rest in the earth the same day; for the man who undergoes hanging is cursed by God; so do not make unclean the land which the Lord your God is giving you for your heritage.

If any man among you becomes unclean through anything which has taken place in the night, he is to go out from the tent-circle and keep outside it:

For the Lord your God is walking among your tents, to keep you safe and to give up into your hands those who are fighting against you; then let your tents be holy, so that he may see no unclean thing among you, and be turned away from you

No part of these things has been used for food in a time of weeping, or put away when I was unclean, or given for the dead: I have given ear to the voice of the Lord my God, and have done all you have given me orders to do.
