Bamidbar 1:1-3

Orthodox Jewish Bible

1 And Hashem spoke unto Moshe in the midbar of Sinai, in the Ohel Mo’ed, on the first day of the second month, in the second year after they were come out of Eretz Mitzrayim, saying,

² Take ye the rosh (top amount, census) of kol Adat Bnei Yisroel after their mishpekhot, by the bais of their avot, with the number of their shmot, every zachar by their head count;

³ From twenty years old and upward, all that are ablebodied to serve in tzava b’Yisroel (army in Yisroel); thou and Aharon shall number them by their tzva’ot (legions).
