Leviticus 11:44-47

For I am Jehovah your God: sanctify yourselves therefore, and be ye holy; for I am holy: neither shall ye defile yourselves with any manner of creeping thing that moveth upon the earth. For I am Jehovah that brought you up out of the land of Egypt, to be your God: ye shall therefore be holy, for I am holy. This is the law of the beast, and of the bird, and of every living creature that moveth in the waters, and of every creature that creepeth upon the earth; to make a distinction between the unclean and the clean, and between the living thing that may be eaten and the living thing that may not be eaten.
