Leviticus 11:22-26

Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.

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

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

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

The carcases of every beast which divideth the hoof, and is not clovenfooted, nor cheweth the cud, are unclean unto you: every one that toucheth them shall be unclean.
