And the priest the son of Aaron shall be with the Levites, when the Levites take tithes: and the Levites shall bring up the tithe of the tithes unto the house of our God, to the chambers, into the treasure house.

A priest of Aaron’s line is to accompany the Levites when they collect the tenth, and the Levites are to bring a tenth of these tithes to the storerooms of the treasury in the house of our God.
