Kommentar zu Schemot 16:24

ולא הבאיש, even the worms which would normally become manifest in short order. לא היתה בו, did not materialise on it.

ורמה לא היתה בו, “and no worms had developed on it.” This verse is an allusion to our tradition that on the Sabbath the corpses are not being disturbed by worms (compare Torah Shleimah note 132). The expression ורמה occurs only twice in the whole Bible, once here and the other time in Job 21,26 ורמה תכסה עליהם, “and worms cover them.” The verse in Job describes the state of corpses during the six days of the week; our verse describes the state of corpses on the Sabbath.
