Leviticus 10:7-9

New Revised Standard Version, Anglicised Catholic Edition

⁷ You shall not go outside the entrance of the tent of meeting, or you will die; for the anointing-oil of the Lord is on you.’ And they did as Moses had ordered.

⁸ And the Lord spoke to Aaron: 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.
