Isaiah 58:3-5 Catholic Public Domain Version (CPDV)

3. "Why have we fasted, and you have not taken notice? Why have we humbled our souls, and you have not acknowledged it?" Behold, in the day of your fasting, your own will is found, and you petition for payment from all your debtors.

4. Behold, you fast with strife and contention, and you strike with the fist impiously. Do not choose to fast as you have done even to this day. Then your outcry will be heard on high.

5. Is this a fast such as I have chosen: for a man to afflict his soul for a day, to contort his head in a circle, and to spread sackcloth and ashes? Should you call this a fast and a day acceptable to the Lord?
