Leviticus 10:8-15 - Lasting Statutes

⁸ Then the Lord spoke to Aaron, ⁹ "Do not drink wine or strong drink, you and your sons with you, when you enter into the Meeting Tent, so that you do not die, which is a perpetual statute throughout your generations, ¹⁰ as well as to distinguish between the holy and the common, and between the unclean and the clean, ¹¹ and to teach the Israelites all the statutes that the Lord has spoken to them through Moses."

¹² Then Moses spoke to Aaron and to Eleazar and Ithamar, his remaining sons, "Take the grain offering which remains from the gifts of the Lord and eat it unleavened beside the altar, for it is most holy. ¹³ You must eat it in a holy place because it is your allotted portion and the allotted portion of your sons from the gifts of the Lord, for this is what I have been commanded. ¹⁴ Also, the breast of the wave offering and the thigh of the contribution offering you must eat in a ceremonially clean place, you and your sons and daughters with you, for they have been given as your allotted portion and the allotted portion of your sons from the peace offering sacrifices of the Israelites. ¹⁵ The thigh of the contribution offering and the breast of the wave offering they must bring in addition to the gifts of the fat parts to wave them as a wave offering before the Lord, and it will belong to you and your sons with you for a perpetual statute just as the Lord has commanded."
