Exodus 16:20

ויותרו אנשים BUT SOME MEN LEFT OF IT — Dathan and Abiram (Shemot Rabbah 24:10; cf. Rashi on Exodus 2:13). וירם תולעים AND IT BRED WORMS — the word וירם is of the same meaning and root as רִמָּה, worm. ויבאש AND IT STANK — This is an inverted verse, because first it must have stunk and afterwards have become wormy, just as it is said, (v. 24) “And it did not stink and there was no worm therein — for this is the way of all things that become wormy (Mekhilta).

וְלֹא־שָׁמְע֣וּ אֶל־מֹשֶׁ֗ה וַיּוֹתִ֨רוּ אֲנָשִׁ֤ים מִמֶּ֙נּוּ֙ עַד־בֹּ֔קֶר וַיָּ֥רֻם תּוֹלָעִ֖ים וַיִּבְאַ֑שׁ וַיִּקְצֹ֥ף עֲלֵהֶ֖ם מֹשֶֽׁה׃

But they hearkened not to Moshe; but some of them left of it until the morning, and it bred worms, and stank: and Moshe was angry with them.
