A priest descended from Aaron is to accompany the Levites when they receive the tithes, and the Levites are to bring a tenth of the tithes up to the house of our God, to the storerooms of the treasury.
This is always to be the perpetual share from the Israelites for Aaron and his sons. It is the contribution the Israelites are to make to the Lord from their fellowship offerings.
The best of all the firstfruits and of all your special gifts will belong to the priests. You are to give them the first portion of your ground meal so that a blessing may rest on your household.
You must not eat any bread, or roasted or new grain, until the very day you bring this offering to your God. This is to be a lasting ordinance for the generations to come, wherever you live.
“Speak to the Levites and say to them: ‘When you receive from the Israelites the tithe I give you as your inheritance, you must present a tenth of that tithe as the Lord’s offering.
