Leviticus 11:41-45

⁴¹Everything which goes flat on its body on the earth is disgusting, and is not to be used for food.

⁴²Whatever goes on its stomach or on four feet or has a great number of feet, even all those going flat on the earth, may not be used for food, for they are disgusting.

⁴³You are not to make yourselves disgusting with anything which goes about flat on the earth; you may not make yourselves unclean with them, in such a way that you are not holy to me.

⁴⁴For I am the Lord your God: for this reason, make and keep yourselves holy, for I am holy; you are not to make yourselves unclean with any sort of thing which goes about flat on the earth.

⁴⁵For I am the Lord, who took you out of the land of Egypt, to be your God; so be you holy, for I am holy.
