Numbers 26:1-4

¹that the Lord spake to Mosheh and to Elazar bar Aharon the priest, saying:

²Take the account of all the congregation of the sons of Israel, from a son of twenty years and upwards by the house of their fathers, everyone that goeth out with the host in Israel.

³And Mosheh and Elazar the priest spake with them, and directed to number them in the plains of Moab, by the Jordan (over against) Jericho, saying:

⁴From a son of twenty years and upward, as the Lord commanded Mosheh, and the sons of Israel who went forth from the land of Mizraim.
