3:8ג׳:ח׳
1 א

מְלֻמְּדֵי מִלְחָמָה. מִלְחַמְתָּהּ שֶׁל תּוֹרָה, וְכֵן הַכֹּהֲנִים הַסּוֹבְבִים אוֹתָהּ הַחוֹנִים סְבִיבוֹת הַמִּשְׁכָּן, מְלֻמְּדֵי סֵדֶר עֲבוֹדָתָם:

Skilled in battle. The battle of Torah, and likewise, the kohanim who surround it, who camp around the Tabernacle, are skilled in the order of their service.

2 ב

אִישׁ חַרְבּוֹ. כְּלֵי זֵינוֹ הֵן מְסֹרֶת וְסִימָנִים, שֶׁמַּעֲמִידִים עַל יָדָם אֶת הַגִּרְסָא וְהַמְסוֹרָה שֶׁלֹּא תִשְׁתַּכַּח:

Each with his sword. His weapons are the Masorah [i.e., tradition] and the mnemonics, by which they preserve the correct version and the traditional rendition, so that it will not be forgotten.

3 ג

מִפַּחַד בַּלֵּילוֹת. פֶּן יִשְׁכָּחוּהָ, וְיָבוֹאוּ עֲלֵיהֶם צָרוֹת וְכֵן הוּא אוֹמֵר: "נַשְּׁקוּ בַר פֶּן יֶאֱנַף וְתאבְדוּ דֶרֶךְ":

For fear of the nights. For if they forget it, and troubles will befall them. And similarly it states, “Arm yourselves with the grain lest He become angry and you lose the way.”10I.e., study the Torah.
