Leviticus 11:21-25

21Yet these may ye eat of every flying creeping thing that goeth upon all four, which have legs above their feet, to leap with upon the earth; 22Even these of them ye may eat; the locust after its kind, and the bald locust after its kind, and the beetle after its kind, and the grasshopper after its kind. 23But all other flying creeping things, which have four feet, shall be an abomination to you. 24And for these ye shall be unclean: whoever toucheth the carcase of them shall be unclean until the evening. 25And whoever beareth any of the carcase of them shall wash his clothes, and be unclean until the evening.
