Esther 4:3; Esther 4:16

3 And as news of the king’s decree reached all the provinces, there was great mourning among the Jews. They fasted, wept, and wailed, and many people lay in burlap and ashes.

16 “Go and gather together all the Jews of Susa and fast for me. Do not eat or drink for three days, night or day. My maids and I will do the same. And then, though it is against the law, I will go in to see the king. If I must die, I must die.”
