What does Leviticus 11:27 mean?

And whatsoever goeth upon its paws, among all beasts that go on all fours, they are unclean unto you: whoso toucheth their carcass shall be unclean until the even.

And whatsoever goeth upon his paws, among all manner of beasts that go on all four, those are unclean unto you: whoso toucheth their carcase shall be unclean until the even.

And whatsoever goeth upon its paws, among all beasts that go on all fours, they are unclean unto you: whoso toucheth their carcass shall be unclean until the even.

Any four-footed beast which goes on the ball of its foot, is unclean to you: anyone touching the dead body of one of these will be unclean till evening.

`And any one going on its paws, among all the beasts which are going on four--unclean they <FI>are<Fi> to you; any one who is coming against their carcase is unclean until the evening;

That which walketh upon hands of all animals which go on all four, shall be unclean: he that shall touch their carcasses shall be defiled until evening.

And whatever goeth on its paws, among all manner of beasts that go upon all four, those are unclean unto you: whoever toucheth their carcase shall be unclean until the even.
