Leviticus 20:25-26

25 aYou shall therefore separate the clean beast from the unclean, and the unclean bird from the clean. You shall not make yourselves detestable by beast or by bird or by anything with which the ground crawls, which I have set apart for you to hold unclean. 26 bYou shall be holy to me, cfor I the Lord am holy and have separated you from the peoples, that you should be mine.
