Leviticus 11:20-25

²⁰All fowls that creep, going upon all four, shall be an abomination unto you.

²¹Yet 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;

²²Even 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.

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.
