Leviticus 10:8-11
Leviticus 10:8-11 ESV
And the LORD spoke to Aaron, saying, “Drink no wine or strong drink, you or your sons with you, when you go into the tent of meeting, lest you die. It shall be a statute forever throughout your generations. You are to distinguish between the holy and the common, and between the unclean and the clean, and you are to teach the people of Israel all the statutes that the LORD has spoken to them by Moses.”
