Esther 4:15-17 NIV
Then Esther sent this reply to Mordecai: “Go, gather together all the Jews who are in Susa, and fast for me. Do not eat or drink for three days, night or day. I and my attendants will fast as you do. When this is done, I will go to the king, even though it is against the law. And if I perish, I perish.”
So Mordecai went away and carried out all of Esther’s instructions.
