Keil & Delitzsch, on Esth 2:1

When, after these things, the wrath of King Ahashverosh was laid (שׁך, from שׁכך, to be sunk, spoken of wrath to be laid), he remembered Vashti and what she had done, and what was decreed against her (גּזר, to determine, to decree irrevocably; comp. גּזרה, Dan 4:14); a desire for reunion with her evidently making itself felt, accompanied perhaps by the thought that she might have been too harshly treated. To prevent, then, a return of affection for his rejected wife ensuing, - a circumstance which might greatly endanger all who had concurred in effecting her repudiation, - the servants of the king, i.e., the court officials who were about him, said: "Let there be young maidens, virgins fair to look on, sought for the king." בּתוּלות, virgins, is added to נערות, the latter word signifying merely young women of marriageable age. Est 2:3. "And let the king appoint (ויפקד is the continuation of יבקּשׁוּ) officers in all the provinces of his kingdom, that they may gather together every virgin who is fair to look on to the citadel of Susa, to the house of the women, unto the hand of Hega the king's eunuch, the keeper of the women, and let them appoint their things for purification; and let the maiden which pleaseth the king be queen instead of Vashti." To the hand of Hega, i.e., to his care and superintendence, under which, as appears from Est 2:12, every maiden received into the house of the women had to pass a year before she was brought before the king. Hega (called Hegai, Est 2:8 and Est 2:15) was an eunuch, the keeper of the women, i.e., superintendent of the royal harem. ונתון is the infin. abs., used instead of the verb. fin. to give prominence to the matter: let them appoint. תּמרקום, from מרק, to rub, to polish, signifies purification and adornment with all kind of precious ointments; comp. Est 2:12. This speech pleased the king, and he acted accordingly.
