Leviticus 11:21-25

21Yet these may ye eat of all winged creeping things that go 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 its kind, and the bald locust after its kind, and the cricket after its kind, and the grasshopper after its kind.

23But all winged creeping things, which have four feet, are an abomination unto you.

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

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