Numbers 18:9-11

9That part of the most holy offerings which is not burned belongs to you. It may come from a grain offering, an offering for sin, or a guilt offering. Whatever is brought to me as a most holy offering will belong to you and your sons.

10Eat it in a most holy place. Any male may eat it. You must consider it holy.

11“The contributions that come as gifts taken from the offerings presented by the Israelites are also yours. I am giving these to you, your sons, and your daughters. They will always be yours. Anyone in your household who is clean  may eat them.
