Numbers 18:10-14

As the most holy gifts you shall eat it; every male shall eat it. It shall be holy to you.

This also is yours, the offering of their gift, that is, all the wave offerings of the sons of Israel; I have given them to you and to your sons and daughters with you as a permanent allotment. Everyone of your household who is clean may eat it.

All the best of the fresh oil and all the best of the fresh wine and of the grain, the first fruits of what they give to the Lord, I have given them to you.

The first ripe fruits of all that is in their land, which they bring to the Lord, shall be yours; everyone of your household who is clean may eat it.

Everything banned from secular use in Israel shall be yours.
