Numbers 18:8; Numbers 18:11; Numbers 18:19

8 Then the LORD said to Aaron, “I myself have put you in charge of the offerings presented to me; all the holy offerings the Israelites give me I give to you and your sons as your portion, your perpetual share.

11 “This also is yours: whatever is set aside from the gifts of all the wave offerings of the Israelites. I give this to you and your sons and daughters as your perpetual share. Everyone in your household who is ceremonially clean may eat it.

19 Whatever is set aside from the holy offerings the Israelites present to the LORD I give to you and your sons and daughters as your perpetual share. It is an everlasting covenant of salt before the LORD for both you and your offspring.”
