20. And Moshe, and Aharon, and Kol Adat Bnei Yisroel, did with the Levi'im according unto all that Hashem commanded Moshe concerning the Levi'im, so did the Bnei Yisroel unto them.
21. And the Levi'im purified themselves, and they immersed their clothes; and Aharon offered them as a tenufah before Hashem; and Aharon made kapporah for them to make them tahor.
22. And after that went the Levi'im in to do their Avodah in the Ohel Mo'ed before Aharon, and before his Banim; just as Hashem had commanded Moshe concerning the Levi'im, so did they with them.
23. And Hashem spoke unto Moshe, saying,
24. This is it that belongeth unto the Levi'im: from twenty and five years old and upward they shall enter to perform service in the Avodat Ohel Mo'ed;
25. And from the age of fifty years they shall retire from the service of the Avodah and shall serve no more;
26. But shall assist with their brethren in the Ohel Mo'ed, in performing their duties, and shall do no Avodah. Thus shalt thou do with the Levi'im regarding their duties.
