As we come to the close of Shabbas Mishpatim, I will ask a question that I am sure has troubled many.
The verse (23:31) tells us:
ושתי את גבולך מים סוף ועד ים פלשתים וממדבר עד הנהר
Vashti: Your boundaries [extend] from Yam Suf until Yam Pelishtim, and from the desert until the river.
How is it possible that Vashti, the wife of Achashverosh, had these boundaries, while elsewhere (Ester 1:1) we are told that Achashverosh ruled from Hodu until Kush? (Rashi there says that Achashverosh was not from royal descent; he had gotten the kingdom from marrying Vashti, so Vashti should have the amount ruled by Achashverosh.)
