Numbers 1:19

וַיִּקַּח מֹשֶׁה וְאַהֲרֹן אֵת הָאֲנָשִׁים הָאֵלֶּה אֲשֶׁר נִקְּבוּ בְּשֵׁמֽוֹת

And Moses and Aaron took these men that are pointed out by name.

וְאֵת כָּל־הָעֵדָה הִקְהִילוּ בְּאֶחָד לַחֹדֶשׁ הַשֵּׁנִי וַיִּתְיַֽלְדוּ עַל־מִשְׁפְּחֹתָם לְבֵית אֲבֹתָם בְּמִסְפַּר שֵׁמוֹת מִבֶּן עֶשְׂרִים שָׁנָה וָמַעְלָה לְגֻלְגְּלֹתָֽם

And they assembled all the congregation together on the first day of the second month, and they declared their pedigrees after their families, by their fathers’houses, according to the number of names, from twenty years old and upward, by their polls.

וַיִּהְיוּ בְנֵֽי־רְאוּבֵן בְּכֹר יִשְׂרָאֵל תּוֹלְדֹתָם לְמִשְׁפְּחֹתָם לְבֵית אֲבֹתָם בְּמִסְפַּר שֵׁמוֹת לְגֻלְגְּלֹתָם כָּל־זָכָר מִבֶּן עֶשְׂרִים שָׁנָה וָמַעְלָה כֹּל יֹצֵא צָבָֽא

And the children of Reuben, Israel’s first-born, their generations, by their families, by their fathers’houses, according to the number of names, by their polls, every male from twenty years old and upward, all that were able to go forth to war;

פְּקֻדֵיהֶם לְמַטֵּה רְאוּבֵן שִׁשָּׁה וְאַרְבָּעִים אֶלֶף וַחֲמֵשׁ מֵאֽוֹת

those that were numbered of them, of the tribe of Reuben, were forty and six thousand and five hundred.
