Numbers 8:21-26

21 The Levites purified themselves and washed their clothes, and Aaron dedicated them as a special gift to the Lord. He also performed the ritual of purification for them.
22 The people did everything the Lord had commanded Moses concerning the Levites. And so the Levites were qualified to work in the Tent under Aaron and his sons.
23 The Lord said to Moses,
24 "From the age of twenty-five each Levite shall perform his duties in the Tent of my presence,
25 and at the age of fifty he shall retire.
26 After that, he may help his fellow Levites in performing their duties in the Tent, but he must not perform any service by himself. This is how you are to regulate the duties of the Levites."

Numbers 8:21-26 Meaning and Commentary

INTRODUCTION TO NUMBERS 8

In this chapter orders are given for the lighting the seven lamps of the candlestick, Nu 8:1-4; and for the consecration of the Levites to their office, by a purification of them, Nu 8:5-8; by a separation of them from the children of Israel, and the imposition of their hands on them, and of the hands of the Levites on the offerings offered for them, Nu 8:9-15; and being thus given to the Lord, and claimed as his, instead of the firstborn of Israel, they are given to Aaron and his sons to do service in the tabernacle, Nu 8:16-22; and their age at which they were to enter into service and cease from it is fixed, Nu 8:23-26.
