民数記 26:62

כי לא התפקדו בתוך בני ישראל FOR THEY WERE NOT NUMBERED AMONGST THE CHILDREN OF ISRAEL, that they should also be numbered from twenty years old and upwards. What was the reason that they were not numbered from twenty years old? כי לא נתן להם נחלה BECAUSE NO INHERITANCE WAS TO BE GIVEN THEM, while those who were counted from twenty years old were persons who were recipients of an inheritance, as it is said, (v. 54) “to everyone shall his inheritance be given according to those that were numbered of them”, (consequently the Levites had to form a different group for the census).

וַיִּהְי֣וּ פְקֻדֵיהֶ֗ם שְׁלֹשָׁ֤ה וְעֶשְׂרִים֙ אֶ֔לֶף כׇּל־זָכָ֖ר מִבֶּן־חֹ֣דֶשׁ וָמָ֑עְלָה כִּ֣י ׀ לֹ֣א הׇתְפָּקְד֗וּ בְּתוֹךְ֙ בְּנֵ֣י יִשְׂרָאֵ֔ל כִּ֠י לֹא־נִתַּ֤ן לָהֶם֙ נַחֲלָ֔ה בְּת֖וֹךְ בְּנֵ֥י יִשְׂרָאֵֽל׃

And those that were numbered of them were twenty three thousand, all males from a month old and upward: for they were not numbered among the children of Yisra᾽el, because there was no inheritance given them among the children of Yisra᾽el.
