Leviticus 11:26-28 - Inedible Land Quadrupeds
26 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. 27 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. 28 Anyone who takes away the dead body of one of these is to have his clothing washed and be unclean till evening.
