Numbers 18:9-10

18:9 Of all the most holy offerings reserved ¹  from the fire this will be yours: Every offering of theirs, whether from every grain offering or from every purification offering or from every reparation offering which they bring to me, will be most holy for you and for your sons. 18:10 You are to eat it as a most holy offering; every male may eat it. It will be holy to you.

[18:9]  ¹ tn Heb “from the fire.” It probably refers to those parts that were not burned.
