Leviticus 10:9-11

LITV(i) 9 You shall not drink wine and strong drink, you nor your sons with you, as you go into the tabernacle of the congregation, and you shall not die; a never ending statute throughout your generations; 10 and to make a distinction between the holy and profane, and between the unclean and the clean; 11 and to teach the sons of Israel all the statutes which Jehovah has spoken to them by the hand of Moses.
