Esther 4:15-17

Then Esther told them to reply to Mordecai, “Go, gather all the Jews to be found in Susa, and hold a fast on my behalf, and do not eat or drink for three days, night or day. I and my young women will also fast as you do. Then 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.
