John Chrysostom
If we accumulate earthly treasures, it is no longer the earthly worm that will consume them, as was the case with the manna, but rather the worm of fire. Thus, we must take every precaution to prevent becoming sustenance for worms.
And Moses said to them: Let no man leave thereof till the morning.
וַיֹּ֥אמֶר מֹשֶׁ֖ה אֲלֵהֶ֑ם אִ֕ישׁ אַל־יוֹתֵ֥ר מִמֶּ֖נּוּ עַד־בֹּֽקֶר׃
