Bamidbar 1:2-4

Orthodox Jewish Bible

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).

⁴ And with you there shall be a man of every tribe; every one Rosh of the bais of his Avot.
