20 So Moses, Aaron and the entire community of Bnei-Yisrael did so with the Levites. All that Adonai had commanded Moses regarding the Levites, so Bnei-Yisrael did to them.
21 The Levites also purified themselves from sin and washed their clothes. Aaron presented them as a wave offering before Adonai, and, he made atonement for them to purify them.
22 After that, the Levites came to do their tasks before Aaron and his sons in the Tent of Meeting, just as Adonai had commanded Moses concerning the Levites.
23 Adonai again spoke to Moses saying,
24 “This is for the Levites. Men 25 years old and upward are to present themselves for service to work in the Tent of Meeting.
25 But at the age of 50 he is to retire from his service and work no longer.
26 He may assist his brothers in the Tent of Meeting to do their duties, but he himself will no longer do the work. Thus, you are to assign to the Levites their responsibilities.”
