And the priest, the son of Aaron, shall be with the Levites when [they] receive tithes, and [they] shall bring one-tenth of the tithes to the house of our God, to the chambers, into the storehouse.
It shall be for Aaron and his sons as their due portion from the Israelites perpetually, an offering from the Israelites of their peace and thanksgiving sacrifices, their offering to the Lord.
And the first of all the firstfruits of all kinds, and every offering of all kinds from all your offerings, shall belong to the priests. You shall also give to the priest the first of your coarse meal and bread dough, that a blessing may rest on your house.
And you shall eat neither bread nor parched grain nor green ears, until this same day when you have brought the offering of your God; it is a statute forever throughout your generations in all your houses.
You shall set apart a cake made of the first of your coarse meal as a gift [to the Lord]; as an offering set apart from the threshing floor, so shall you lift it out or heave it.
Moreover, you shall say to the Levites, When you take from the Israelites the tithe which I have given you from them for your inheritance, then you shall present an offering from it to the Lord, even a tenth of the tithe [paid by the people].
