And thou shalt set the Levites before Aaron, and before his sons, and offer them for an offering unto the LORD.
The direction is to set the Levites before Aaron and before his sons and to offer them as an offering to the Lord. In that offering they are given as an offering from Israel itself. The direction belongs to the instructions for the Levites' sanctuary service, and it concerns their purification and consecration for service to the Lord. Their consecration for that sanctuary service was completed when the assembly laid hands upon the Levites and sacrifices were slain. So consecrated, the Levites served the priests in their work, while the priestly office itself belonged to Aaron's descendants alone.
