Esther 2:20

Esther had not showed her kindred nor her people, as Mordecai
had charged her
As not before, so neither since she was made queen, see ( Esther 2:10 ) , though, according to the Targums, she was urged to it by the king himself:

for Esther did the commandment of Mordecai, like as when she was
brought up with him:
which showed great humility in her, notwithstanding her advancement, great respect to him, and a sense of gratitude for the kindness he had shown; and this charge to her was still continued by Mordecai, partly that she might not fall into contempt, and partly to prevent hatred and envy to the Jewish nation, through her promotion; but chiefly so it was ordered in Providence, the proper time being not yet come.
