Continuing his thoughts on the previous verse, the Vilna Gaon writes that Esther’s rising up alludes to the end of the morning prayer service, and her standing alludes to the kaddish prayer.
Similarly, the Dena Pishra explains that Esther was standing here because she was pleading before H-Shem, and this is why the verse refers to Him as King.
The Shelah writes that we should stand in prayer before H-Shem the same way we do before a human king.
R’ Moshe Feinstein would famously stand still during prayer instead of shukeling back and forth, as many do. The source of this custom was an incident in which, as a rabbi in communist Russia, he was called before the police commandant. He recalled that one of the most frightening events of his life was standing there, stock still, unable to move. Realizing that one is standing before an authority should cause one to avoid any movement.
- The Alshich writes, consistent with his previous interpretation, that Achashverosh’s youths respond that it is Haman who is in charge, and he’s here now.
- M’nos HaLevi, however, explains that the the youths were saying that Haman actually means to cause harm to the king, and he’s standing there waiting to see that all are sleeping and it is an opportune time to secretly strike at the king.
- According to M’nos HaLevi, the significance of Esther standing in this location is that Esther was standing in prayer.
- In fact, the Targum Sheni elaborates on the actual words Esther uttered, mostly paraphrases Tehillim 22.
