Leviticus 10:8-15 - Lasting Statutes
8 And the LORD spake unto Aaron, saying, 9 "Drink no wine nor strong drink - neither thou nor thy sons with thee - when ye go into the tabernacle of witness, lest ye die. And let it be a law forever unto your children after you: 10 that ye may put difference between holy and unholy, and between unclean and clean, 11 and that ye may teach the children of Israel all the ordinances which the LORD hath commanded them by the hands of Moses."
12 And Moses said unto Aaron, and unto Eleazar and Ithamar his sons that were left, "Take the meat offering that remaineth of the sacrifices of the LORD, and eat it without leaven beside the altar, for it is most holy: 13 eat it therefore in the holy place, because it is thy duty and thy sons' duty of the sacrifice of the LORD: for so I am commanded. 14 And the wavebreast and heaveshoulder eat in a clean place: both thou and thy sons and thy daughters with thee. For it is thy duty, and thy sons' duty with thee, of the peace offerings of the children of Israel. 15 For the heaveshoulder and the wavebreast which they bring with the sacrifices of the fat, to wave it before the LORD, shall be thine and thy sons' with thee, and be a law for ever, as the LORD hath commanded."
