Then Esther spoke to Hathach and gave him a message for Mordecai, saying, "All the king's servants and the people of the king's provinces know that if any man or woman goes to the king inside the inner court without being called, there is but one law—all alike are to be put to death. Only if the king holds out the golden scepter to someone, may that person live. I myself have not been called to come in to the king for thirty days." When they told Mordecai what Esther had said, Mordecai told them to reply to Esther, "Do not think that in the king's palace you will escape any more than all the other Jews. For if you keep silence at such a time as this, relief and deliverance will rise for the Jews from another quarter, but you and your father's family will perish. Who knows? Perhaps you have come to royal dignity for just such a time as this." Then Esther said in reply to Mordecai, "Go, gather all the Jews to be found in Susa, and hold a fast on my behalf, and neither eat nor drink for three days, night or day. I and my maids will also fast as you do. After that I will go to the king, though it is against the law; and if I perish, I perish." Mordecai then went away and did everything as Esther had ordered him. (NRSV 4:10-17)
Again Esther spake unto Hatach, and gave him commandment unto Mordecai; All the king's servants, and the people of the king's provinces, do know, that whosoever, whether man or women, shall come unto the king into the inner court, who is not called, there is one law of his to put him to death, except such to whom the king shall hold out the golden sceptre, that he may live: but I have not been called to come in unto the king these thirty days. And they told to Mordecai Esther's words. Then Mordecai commanded to answer Esther, Think not with thyself that thou shalt escape in the king's house, more than all the Jews. For if thou altogether holdest thy peace at this time, then shall there enlargement and deliverance arise to the Jews from another place; but thou and thy father's house shall be destroyed: and who knoweth whether thou art come to the kingdom for such a time as this? Then Esther bade them return Mordecai this answer, Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish. So Mordecai went his way, and did according to all that Esther had commanded him. (KJV 4:10-17)
Here Esther almost wimps out as she momentarily loses heart. But Mordecai urges her to make the right decision. Also, this might be one of the moments where the idea of a divine plan is implicitly in the background.
