The Miracle of a Woman Keeping a Secret

לא הגידה אסתר את עמה ואת מולדתה כי מרדכי צוה עליה אשר לא תגיד
“Esther did not reveal her people or her kindred, for Mordechai had told her not to reveal it.” (Esther 2:10)

It is well-known that Hashem’s name doesn’t appear a single time in the entire Megillah. This peculiarity is traditionally explained as hinting to the fact that the Megillah contains only “hidden miracles” but is lacking open miracles which more clearly demonstrate Hashem’s Providence. Rav Eizel Charif sharply suggested that nevertheless, one clear miracle remains. Mordechai told Esther not to reveal her religion or nationality, and a woman actually managed to keep a secret!
