אִיזֶבֶל
This seems rather far-fetched. I am, however, still inclined to give the sense of "pure, unpolluted," to
אִיזֶבֶל
, but on different grounds.
זֶבֶל
has another sense, κοπρος, particularly of camels, from the round form; and the word was common, in the later Hebrew, in that sense. Hence the evil spirit is called
בַעַל־זְבוּל
, a contemptuous name, instead of
בַעַל־זְבוּב
= Βεελζεβουλ instead of Βεελζεβουβ (Matt. xii. 24.).
