John Gill Commentary Esther 2:9

"And the maiden pleased him, and she obtained kindness of him; and he speedily gave her her things for purification, with her portions, and the seven maidens who were meet to be given her out of the king`s house: and he removed her and her maidens to the best place of the house of the women." — Esther 2:9 (ASV)

And the maiden pleased him
Not the king, into whose presence she was not yet introduced, but the chamberlain; her beauty and her behaviour recommended her to him, and he concluded within himself that she was the person that of all would be acceptable to the king:

and she obtained kindness of him :
had favours shown others had not:

and he speedily gave her things for purification ;
as oil, spices, &c. that she might be the sooner fitted to be had into the king's presence:

with such things as belonged to her ;
food and drink from the king's table; the Targum interprets it gifts, as chains and royal apparel:

and seven maidens, which were given her, out of the king's house ;
to wait upon her the seven days of the week, as the same Targum:

and he preferred her and her maids unto the best place of the house of
the women ;
removed her and them to it, which was the most splendid, had large, airy, and pleasant rooms.
