Esther 4:15-16

¹⁵Then Esther told them to reply to Mordecai, ¹⁶“Go, assemble all the Jews who are found in Susa, and fast for me; do not eat or drink for three days, night or day. I and my maidens also will fast in the same way. And thus I will go in to the king, which is not according to the law; and if I perish, I perish.”
