Leviticus 11:6

11:5 the rock hyrax, because it chews the cud but does not have cloven hooves, is unclean to you;

11:6 the hare, because it chews the cud but does not have cloven hooves, is unclean to you;

11:7 and the swine, though it divides the hoof, having cloven hooves, yet does not chew the cud, is unclean to you.
