Leviticus 11:21-25

Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap withal upon the earth;

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.
