John Gill Commentary Leviticus 10:5

"So they drew near, and carried them in their coats out of the camp, as Moses had said." — Leviticus 10:5 (ASV)

So they went near
To the place where the bodies lay, having an order from Moses so to do, let them have been where they will;

and carried them in their coats out of the camp, as Moses had said ;
or bid them do; they took them up in their clothes as they found them, and carried them in them; not that these men carried them in their own coats, but in the coats of the dead, as Jarchi expresses it; and had them without the camp, and there buried them, probably in their coats in which they had sinned, and in which they died: the Targum of Jonathan says, they carried them on iron hooks in their coats, and buried them without the camp.
