LEVITICUS 11:43-47

⁴³Ye 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.

⁴⁴For I am the LORD 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.

⁴⁵For I am the LORD that brought you up out of the land of Egypt, to be your God: ye shall therefore be holy, for I am holy.

⁴⁶This is the law of the beast, and of the fowl, and of every living creature that moveth in the waters, and of every creature that creepeth upon the earth:

⁴⁷to make a difference between the unclean and the clean, and between the living thing that may be eaten and the living thing that may not be eaten.
