Deuteronomy 14:7

14:7 However, you may not eat the following animals among those that chew the cud or those that have divided hooves: the camel, the hare, and the rock badger. (Although they chew the cud, they do not have divided hooves and are therefore ritually impure to you).

Deuteronomy 23:14

23:14 For the Lord your God walks about in the middle of your camp to deliver you and defeat your enemies for you. Therefore your camp should be holy, so that he does not see anything indecent among you and turn away from you.
