Référence sur Guittin 3:14

מחספס uncovered — and there is no other example of this word in the Scriptures. One may also explain מחספס as having the same meaning as המיסה in (Mishna Bava Metzia 1:8) חפיסה ודלוסקמא, “a valise and chest”, in Mishnaic Heberw, and the meaning would be, that when it became uncovered from the layer of dew they saw that there had been a thin object enclosed in it i. e. enclosed between the two layers of dew. Onkelos tranlates it by מקלף peeled (flaky), taking מחספס in the sense of, and from a similar root as, (Genesis 30:37) “peeling off (מחשף) the white”.
