Esther 4:11 (KJV)

And Hatach came and told Esther the words of Mordecai.

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 woman, 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.
