Esther 4:13-17

And Mordecai told them to answer Esther: “Do not think in your heart that you will escape in the king’s palace any more than all the other Jews. For if you remain completely silent at this time, relief and deliverance will arise for the Jews from another place, but you and your father’s house will perish. Yet who knows whether you have come to the kingdom for such a time as this?” Then Esther told them to reply to Mordecai: “Go, gather all the Jews who are present in Shushan, and fast for me; neither eat nor drink for three days, night or day. My maids and I will fast likewise. And so I will go to the king, which is against the law; and if I perish, I perish!” So Mordecai went his way and did according to all that Esther commanded him.
