Leviticus 10:10 BBE

⁸  And the Lord said to Aaron:

⁹  Take no wine, or strong drink, you or your sons with you, when you go into the Tent of meeting, that it may not be the cause of death to you; this is an order for ever through all your generations.

¹⁰  And make a division between the holy and the common, and between the unclean and the clean;

¹¹  Teaching the children of Israel all the laws which the Lord has given them by the hand of Moses.

¹²  And Moses said to Aaron and to Eleazar and Ithamar, his sons who were still living, Take the rest of the meal offering from the offerings of the Lord made by fire, and take it for your food, without leaven, at the side of the altar, for it is most holy.
