יז וַיֶּאֱהַב הַמֶּלֶךְ אֶת–אֶסְתֵּר מִכָּל–הַנָּשִׁים וַתִּשָּׂא–חֵן וָחֶסֶד לְפָנָיו מִכָּל–הַבְּתוּלוֹת וַיָּשֶׂם כֶּתֶר–מַלְכוּת בְּרֹאשָׁהּ וַיַּמְלִיכֶהָ תַּחַת וַשְׁתִּי
17. And the king loved Esther from all of the women, and she placed favor/grace and kindness before him from all of the virgins and he put the crown of royalty on her head and he coronated her in the place of Vashti.
In the Talmud (Pesachim 22b), Rabbi Akiva famously holds that every “es” is meant to include something else besides what is specifically mentioned in the verse. Rabbi Meir Eisenshtaat says that, in this verse discussing what Achashverosh loved, this “es” is meant to include Esther’s sheid, or demon (as we mentioned before). This is perhaps one more reason that H-Shem inspired Achashverosh to prefer relations at night – in order for him to be unable to see Esther’s demon.
