Pope Shenouda III
The Prophet Daniel fasted (Dan 9:3) and so did the Prophet Ezekiel (Ezek 4:9).
We hear that Nehemiah fasted when he heard that “The wall of Jerusalem is also broken down, and its gates are burned with fire." (Neh. 1:3,4). Thus did Ezra, the scribe and priest, fasting and calling upon the whole population to fast. (Ezra 8:2 1).
The prophetess Anna “did not depart from the temple, but served God with fastings and prayers night and day.” (Luke 2:3 7).
