Leviticus 11:24-28

24‘By [contact with] these you will become unclean; whoever touches their carcasses becomes unclean until the evening (dusk),

25and whoever picks up any of their carcasses shall wash his clothes and be unclean until the evening.

26Concerning all the animals which divide the hoof, but do not have a split hoof, or which do not chew the cud, they are unclean to you; whoever touches them becomes unclean.

27Also all animals that walk on their paws, among all kinds of animals that walk on four legs, are unclean to you; whoever touches their carcasses becomes unclean until the evening,

28and the one who picks up their carcasses shall wash his clothes and be unclean until the evening; they are unclean to you.
