||The entire tally of the Levites was made by Moses and Aaron by families. There were 22,000 males over one month old.
Kol-pekudey haLevi'im asher pakad Moshe ve'Aharon al-pi Adonay lemishpechotam kol-zachar miben-chodesh vamalah shnayim ve'esrim alef.
This is an exact count, as we see in Numbers 3:46. If the number from the sub-tribes of Gershon, Kehoth and Merari are added, however, the total is 22,300, so that 300 are missing. According to tradition, the 300 were first-born Levites, who could not redeem first-born Israelites (Bekhoroth 5a; Rashi).
