Companion question to Why does Tanac"h specifically describe these males as "beautiul"?
Off the top of my head, the pesukim describe the following women as being beautiful:
- Sarah (Bereishis 12:11)
- Rivkah (Bereishis 24:16)
- Rachel (Bereishis 29:17)
- Tamar bas David (Shmuel II:14:27)
- Esther (Esther 2:7)
Additionally, Chazal identify several other beautiful women (Megillah 15a):
- Michal bas Sha'ul
(There may be others, but I can't think of them, so feel free to edit, if needed.)
What is special about these people that Tana"ch and Chazal felt the specific need to describe how beautiful they were? Is there something, in particular, perhaps some hidden or important message as to why we need to know this information? What made these people especially "beautiful," more than other female personalities throughout Tana"ch that are not described this way?
