Commentary for Esther 2:11

And what would be done with her. He [Mordechai] was one of two righteous men to whom a hint of salvation was given; Dovid and Mordechai. Dovid as it is stated, “Even the lion and the bear has your servant slain.”¹²I Shmuel 17:36. He [Dovid] said [to himself], “this incident did not happen to me only that I should rely on it and do battle with this one [Golyas].” And similarly, Mordechai [said to himself], “It did not happen to this righteous woman that she should be taken to a gentile’s bed only that she is destined to rise to save Yisroel.” He therefore repeatedly went around to find out what would be her fate.¹³Esther Rabbah 6:6. Accordingly ומה יעשה בה means “and what would be accomplished through her.”
