Esther 4:3; Esther 4:16

3 Also in all provinces, cities, and places, to which the cruel sentence of the king was come, there was great wailing, fasting, and weeping, and yelling with the Jews, and many Jews used a sackcloth and ashes for their bed. (And in all the provinces, and cities, and places, to which the cruel sentence of the king had come, there was great wailing, and fasting, and weeping, and yelling from the Jews, and many Jews lay in sackcloth and ashes.)

16 Go thou, and gather together all the Jews, which thou findest in Susa, and pray ye for me; eat ye not, that is, fast ye, neither drink ye, in three days and three nights, and I with mine handmaidens shall fast in like manner; and then I not called, shall enter in to the king, and I shall do against the law, and I shall betake me to death and to peril. (Go thou, and gather together all the Jews, whom thou findest in Susa, and pray ye for me; eat ye not, that is, fast ye, and drink ye not, for three days and three nights, and I shall fast with my servantesses in like manner; and then though I be not called, I shall go to the king, and I shall go against the law, and I shall deliver myself unto peril and even death.)
