'Fastings' in the Bible

to establish these days of Purim, in their seasons, as Mordecai the Jew hath established on them, and Esther the queen, and as they had established on themselves, and on their seed -- matters of the fastings, and of their cry.

And I -- in their sickness my clothing is sackcloth, I have humbled with fastings my soul, And my prayer unto my bosom returneth.
