'Unclean' in the Bible
Nevertheless, according to all the desire of thy soul thou mayest slay and eat flesh in all thy gates, according to the blessing of Jehovah thy God which he hath given thee: the unclean and the clean may eat thereof, as of the gazelle, and the hart.
Even as the gazelle and the hart is eaten, so thou shalt eat them: the unclean and the clean alike may eat of them.
Only these ye shall not eat of those that chew the cud, or of those with hoofs cloven and split open: the camel, and the hare, and the rock-badger; for they chew the cud, but have not cloven hoofs they shall be unclean unto you;
and the swine, for it hath cloven hoofs, yet cheweth not the cud it shall be unclean unto you. Of their flesh shall ye not eat, and their carcase shall ye not touch.
but whatsoever hath not fins and scales ye shall not eat: it shall be unclean unto you.
And every winged crawling thing shall be unclean unto you; they shall not be eaten.
In thy gates shalt thou eat it; the unclean and the clean shall eat it alike, as the gazelle and as the hart.
