20Thus did Moses, and Aaron, and all the congregation of the children of Israel, to the Levites: according to all that Yahweh commanded Moses touching the Levites, so did the children of Israel to them.
21The Levites purified themselves from sin, and they washed their clothes: and Aaron offered them for a wave-offering before Yahweh; and Aaron made atonement for them to cleanse them.
22After that went the Levites in to do their service in the tent of meeting before Aaron, and before his sons: as Yahweh had commanded Moses concerning the Levites, so did they to them.
24This is that which belongs to the Levites: from twenty-five years old and upward they shall go in to wait on the service in the work of the tent of meeting:
25and from the age of fifty years they shall cease waiting on the work, and shall serve no more,
26but shall minister with their brothers in the tent of meeting, to keep the charge, and shall do no service. Thus shall you do to the Levites touching their charges.
