Leviticus 10:6-9

Living Bible

⁶ Then Moses said to Aaron and his sons Eleazar and Ithamar, “Do not mourn—do not let your hair hang loose as a sign of your mourning, and do not tear your clothes. If you do, God will strike you dead too, and his wrath will come upon all the people of Israel. But the rest of the people of Israel may lament the death of Nadab and Abihu, and mourn because of the terrible fire the Lord has sent. ⁷ But you are not to leave the Tabernacle under penalty of death, for the anointing oil of Jehovah is upon you.” And they did as Moses commanded.

^8-9 Now the Lord instructed Aaron, “Never drink wine or strong drink when you go into the Tabernacle, lest you die; and this rule applies to your sons and to all your descendants from generation to generation.
