³⁵ From shloshim shanah (thirty years old) and upward even until chamishim shanah (fifty years old) shalt thou number them, every one that entereth into the tz’va (holy militia service of Hashem), to do the work of the Avodah in the Ohel Mo’ed;

³⁶ And those that were numbered of them by their mishpekhot were two thousand seven hundred and fifty.

³⁷ These were they that were numbered of the mishpekhot HaKehati, all that might do service in the Ohel Mo’ed which Moshe and Aharon did number according to the command of Hashem by the hand of Moshe.
