Ta'anit Esther: The Fast of Esther

Mordechai had this message delivered to Esther: “Do not imagine that you … will escape with your life by being in the king’s palace. On the contrary, if you keep silent in this crisis, relief and deliverance will come to the Jews from another quarter, while you and your father’s house will perish. … Perhaps you have attained to royal position for just such a crisis!”    
– Esther: 4:12-14
