And the priest, the descendant of Aaron, shall be with the Levites when the Levites receive the tithes; and the Levites shall bring up a tithe of the tithes to the house of our God, to the chambers of the storehouse.
These things shall be a perpetual ordinance for Aaron and his sons from the Israelites, for this is an offering; and it shall be an offering by the Israelites from their sacrifice of offerings of well-being, their offering to the Lord.
The first of all the first fruits of all kinds, and every offering of all kinds from all your offerings, shall belong to the priests; you shall also give to the priests the first of your dough, in order that a blessing may rest on your house.
You shall eat no bread or parched grain or fresh ears until that very day, until you have brought the offering of your God: it is a statute forever throughout your generations in all your settlements.
You shall speak to the Levites, saying: When you receive from the Israelites the tithe that I have given you from them for your portion, you shall set apart an offering from it to the Lord, a tithe of the tithe.
