Leviticus 11:45-47

New Revised Standard Version Catholic Edition

⁴⁵ For I am the Lord who brought you up from the land of Egypt, to be your God; you shall be holy, for I am holy.

⁴⁶ This is the law pertaining to land animal and bird and every living creature that moves through the waters and every creature that swarms upon the earth, ⁴⁷ to make a distinction between the unclean and the clean, and between the living creature that may be eaten and the living creature that may not be eaten.
