Kommentar zu Bamidbar 11:34

ויקרא את שם המקום קברות התאוה, “he called the name of this place: graves of lust.” The Torah did not identify who it was who bestowed this name on these graves, just as we find that in Genesis 48,1 we do not know who told Joseph that his father had been taken sick, i.e. ויאמר ליוסף, “someone called Joseph.”
