Leviticus 11:42-47

⁴²Whatsoever goeth upon the belly, and whatsoever goeth upon all fours, or whatsoever hath many feet, even all creeping things that creep upon the earth, them ye shall not eat; for they are an abomination.

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 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.

⁴⁵For 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.

⁴⁶This 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;

⁴⁷to 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.
