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.
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 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.
