Leviticus 20:25-26

Revised Standard Version

²⁵ You shall therefore make a distinction between the clean beast and the unclean, and between the unclean bird and the clean; you shall not make yourselves abominable by beast or by bird or by anything with which the ground teems, which I have set apart for you to hold unclean. ²⁶ You shall be holy to me; for I the Lord am holy, and have separated you from the peoples, that you should be mine.
