.י"ג Provisional Beauty

ר' יהושע בן קרחה אמר אסתר ירקרוקת היתה וחוט של חסד משוך עליה

So, אסתר was not the most beautiful woman in the land? What would compel ר' יהושע בן קרחה to say that? The גר"א brilliantly points out that in the discussion (:בבא בתרא ט"ו) of what era the character איוב lived (if at all) ר' יהושע בן קרחה's opinion is that he lived in the time of אחשורוש. And it says (איוב מ"ב:ט"ו) that איוב's daughters were the most beautiful in the entire land. Therefore, according to ר' יהושע בן קרחה it could not possibly be that אסתר was the most beautiful. Certainly, there was some special Divine Providence at play here.
