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.
The priest's son from the family of Aaron will be with the Levites as they collect a portion of people's offerings. The Levites will then give part of what they collected to the temple, storing it in special rooms for treasures.
