מִבֶּ֨ן עֶשְׂרִ֤ים שָׁנָה֙ וָמַ֔עְלָה כָּל־יֹצֵ֥א צָבָ֖א בְּיִשְׂרָאֵ֑ל תִּפְקְד֥וּ אֹתָ֛ם לְצִבְאֹתָ֖ם אַתָּ֥ה וְאַהֲרֹֽן׃
from twenty years old and upward, all that are able to go forth to war in Israel: ye shall number them by their hosts, even thou and Aaron.
Targum Jonathan on Numbers
From each son twenty years and upwards, every one going out in the host in Israel; thou and Aharon number them by their hosts.
