Leviticus 10:9-11

MLV(i) 9 Drink no wine nor strong drink, you, nor your sons with you, when you* go into the tent of meeting, that you* not die–it will be an everlasting statute throughout your* generations– 10 and that you* may make a distinction between the holy and the common and between the unclean and the clean, 11 and that you* may teach the sons of Israel all the statutes which Jehovah has spoken to them by Moses.
