Leviticus 10:9-11

New Revised Standard Version, Anglicised

⁹ Drink no wine or strong drink, neither you nor your sons, when you enter the tent of meeting, that you may not die; it is a statute for ever throughout your generations. ¹⁰ You are to distinguish between the holy and the common, and between the unclean and the clean; ¹¹ and you are to teach the people of Israel all the statutes that the Lord has spoken to them through Moses.
