Esther 2:10

Esther had not showed her people nor her kindred ,.... What nation or family she was of; it not being asked, she was under no obligation to declare it; and being born in Shushan, as very probable, she was taken to be a Persian:

for Mordecai had charged her that she should not show it ; lest she should be despised and ill treated on that account; fearing, if the king knew it, he would not marry her, as Aben Ezra; or rather, as the same writer thinks, that she might keep the law of God privately, observe the sabbath, &c.;
