Ye shall not make yourselves abominable with any creeping thing that creepeth, neither shall ye make yourselves unclean with them, that ye should be defiled thereby.
And God said, Let the waters bring forth abundantly the moving creature that hath life, and let fowl fly above the earth in the open firmament of heaven.
Ye shall therefore separate between the clean beast and the unclean, and between the unclean fowl and the clean: and ye shall not make your souls abominable by beast, or by fowl, or by any thing wherewith the ground teemeth, which I have separated from you as unclean.
