וַֽיִּקְרְב֗וּ וַיִּשָּׂאֻם֙ בְּכֻתֳּנֹתָ֔ם אֶל־מִח֖וּץ לַֽמַּחֲנֶ֑ה כַּאֲשֶׁ֖ר דִּבֶּ֥ר מֹשֶֽׁה׃
Chegaram-se, pois, e levaram-nos como estavam, nas próprias túnicas, para fora do arraial, como Moisés lhes dissera.
Rashi on Leviticus
בכתנתם IN THEIR GARMENTS — in those of the dead (not in their own garments). This tells us that their garments had not been destroyed by fire, but their souls alone (neither their clothing nor bodies showed signs of burning; they had been struck by fire inwardly): there entered into their nostrils something like two threads of fire which burnt them to death (Sifra, Shemini, Mechilta d'Miluim 2 34; Sanhedrin 52a).
Sforno on Leviticus
בכתנותם אל מחוץ למחנה, they did not bother to remove their holy vestments from them seeing that these had already become ritually impure.
Siftei Chakhamim
Of the dead men. As it is written, “בכתנתם (in their tunics),” and every כתונת mentioned in Torah Kohanim (Vayikro) is referring to garments of kehunah. Mishael and Elzafan, however, were Levites and not kohanim; so from where would they have tunics? Rather, it must refer to [the tunics of] the dead men.
