Leviticus 11:43-47

⁴³Ye shall not make yourselves abominable through any crawling thing which crawleth, neither shall ye make yourselves unclean with them, that ye should be defiled thereby.

⁴⁴For I am Jehovah your God; and ye shall hallow yourselves, and ye shall be holy; for I am holy; and ye shall not make yourselves unclean through any manner of crawling thing which creepeth on the earth.

⁴⁵For I am Jehovah who 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 cattle, and of fowl, and of every living soul that moveth in the waters, and of every soul that crawleth on the earth;

⁴⁷to make a difference between the unclean and the clean, and between the beast that is to be eaten and the beast that is not to be eaten.
