'Clean' 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.

All clean birds may be used for food.

But all clean birds you may take.

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.
