Leviticus 11:23-28

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

²⁴And for these ye shall be unclean: whoever toucheth the carcass of them shall be unclean until the evening.

²⁵And whoever beareth aught of the carcass of them shall wash his clothes, and be unclean until the evening.

²⁶The carcasses of every beast which divideth the hoof, and is not cloven-footed, nor cheweth the cud, are unclean to you: every one that toucheth them shall be unclean.

²⁷And whatever goeth upon its paws, among all manner of beasts that go on all four, those are unclean to you: whoever toucheth their carcass shall be unclean until the evening.

²⁸And he that beareth the carcass of them shall wash his clothes, and be unclean until the evening: they are unclean to you.
