Esther 4:3

3 In every province reached by the king's order and decree, there was great mourning among the Jews, with fasting, weeping and wailing, as many lay down on sackcloth and ashes.

Esther 4:16

16 "Go, assemble all the Jews to be found in Shushan, and have them fast for me, neither eating nor drinking for three days, night and day; also I and the girls attending me will fast the same way. Then I will go in to the king, which is against the law; and if I perish, I perish."
