Leviticus 10:10-11 KJV

8And the LORD spake unto Aaron, saying,

9Do not drink wine nor strong drink, thou, nor thy sons with thee, when ye go into the tabernacle of the congregation, lest ye die: it shall be a statute for ever throughout your generations:

10And that ye may put difference between holy and unholy, and between unclean and clean;

11And that ye may teach the children of Israel all the statutes which the LORD hath spoken unto them by the hand of Moses.

12And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meat offering that remaineth of the offerings of the LORD made by fire, and eat it without leaven beside the altar: for it is most holy:

13And ye shall eat it in the holy place, because it is thy due, and thy sons’ due, of the sacrifices of the LORD made by fire: for so I am commanded.
