Behold, you fast for strife and debate, and to smite with the fist of wickedness: [you shall not fast as you do this day, to make your voice to be heard on high].
Is not this the fast that I have chosen?
to loose the bands of wickedness, to undo the heavy burdens, and to let the oppressed go free, and that you break every yoke?
Is it not to deal your bread to the hungry, and that you bring the poor that are cast out to your house?…
Book of Isaiah
Chapter 58
