Midras Imamat 10:5: Sifra

27) (Vayikra 10:5): "And they drew near and they carried them in their (the dead ones') tunics.": We are hereby taught that the L–rd was more solicitous for them in their deaths than in their lives. For if their bodies had been burned and their garments not been intact, they would have been exposed and despised. But their bodies were burned and their garments left intact. Now does this not follow a fortiori: If for these, who had angered the L–rd, having entered before Him against His will, He did thus, how much more so, for the other righteous ones!

34) (Vayikra 10:2): "And a fire came out from before the L–rd": We are hereby taught that a fire came forth from the holy of holies and burned their souls. Abba Yossi b. Dostai says: Two strands of fire came forth from the holy of holies and parted into four, and entered, two into the nostrils of one, and two, into the nostrils of the other, and burned them, but not their garments, it being written (Vayikra 10:2) "and it consumed them," but not their garments. And it is written (Vayikra 10:5) "And they carried them in their tunics": In the tunics of the carried (their garments not having been burned) or the tunics of the carriers? It is, therefore, written (Shemoth 28:40): "And for the sons of Aaron (here, the carried,) shall you make tunics," (and not for the sons of the Levites; here, the carriers).

35 (Vayikra 10:2): "And they died before the L–rd": R. Eliezer says: They died outside (the tent of meeting, in the court of the Israelites and the Cohanim), a place where the Levites are permitted to go, as it is written (Vayikra 10:5) "and they (the Levites) drew near and they carried them in their tunics." Why, then, is it written "and they died before the L–rd"? An angel smote them (in the holy of holies), and pushed them out (of the tent of meeting). R. Akiva says: They died inside, as it is written "and they died before the L–rd." If so, what is the intent of "and they drew near and they carried them in their tunics"? They hurled an iron spear and dragged them and (thus) took them out.
