Jerome, on Isa 58:5

“Is this such a fast as I have chosen: for a man to afflict his soul for a day? is this it, to wind his head about like a circle, and to spread sackcloth and ashes? wilt thou call this a fast, and a day acceptable to the Lord?”

“If you have fasted two or three days, do not think yourself better than others who do not fast. You fast and are angry; the other eats and wears a smiling face. You work off your irritation and hunger in quarrels. He uses food in moderation and gives God thanks.”
