'Division' in the Bible

And make a division between the holy and the common, and between the unclean and the clean;

You may have as food any beast which has a division in the horn of its foot, and whose food comes back into its mouth to be crushed again.

Every beast, in the horn of whose foot there is not a complete division, and whose food does not come back, is unclean to you: anyone touching one of these will be unclean.

So then, make division between the clean beast and the unclean, and between the clean bird and the unclean: do not make yourselves disgusting by any beast or bird or anything which goes flat on the earth, which has been marked by me as unclean for you.
