Bamidbar 4:39-41

Orthodox Jewish Bible

³⁹ From shloshim shanah and upward even until chamishim shanah 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,

⁴⁰ Even those that were numbered of them, throughout their mishpekhot, by the bais of their avot, were two thousand and six hundred and thirty.

⁴¹ These are they that were numbered of the Mishpekhot Bnei Gershon, of all that might do service in the Ohel Mo’ed whom Moshe and Aharon did number according to the command of Hashem.
