²³But all other flying creeping things, which have four feet, shall be an abomination unto you.

²⁴And for these ye shall be unclean: whosoever toucheth the carcase of them shall be unclean until the even.

²⁵And whosoever beareth ought of the carcase of them shall wash his clothes, and be unclean until the even.
