A priest of Aaronic descent must accompany the Levites when they collect the tenth, and the Levites must take a tenth of this offering to the storerooms of the treasury in the house of our God.
This will belong to Aaron and his sons as a regular portion from the Israelites, for it is a contribution. It will be the Israelites’ contribution from their fellowship sacrifices, their contribution to the Lord.
The best of all the firstfruits of every kind and contribution of every kind from all your gifts will belong to the priests. You are to give your first batch of dough to the priest so that a blessing may rest on your homes.
You must not eat bread, roasted grain, or any new grain until this very day, and until you have brought the offering to your God. This is to be a permanent statute throughout your generations wherever you live.
“Speak to the Levites and tell them: When you receive from the Israelites the tenth that I have given you as your inheritance, you must present part of it as an offering to the Lord — a tenth of the tenth.
