Esther 4:3

3 And in every province, wherever the king's command and his decree reached, there was great mourning among the Jews, with fasting and weeping and lamenting, and many of them lay in sackcloth and ashes.

Esther 4:16

16 "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."
