Leviticus 10
9 Ref "Drink no wine nor strong drink, you, nor your sons with you, when you go into the Tent of Meeting, that you don't die: it shall be a statute forever throughout your generations:
10 Ref and that you are to make a distinction between the holy and the common, and between the unclean and the clean;
11 Ref and that you are to teach the children of Israel all the statutes which Yahweh has spoken to them by Moses."
