'Fastings' in the Bible

To confirm these days of Purim in their times appointed, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had decreed for themselves and for their seed, the matters of the fastings and 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.
