Isaiah 58
4 Ref Behold, you fast for strife and contention, and to strike with the fist of wickedness: you don't fast this day so as to make your voice to be heard on high.
5 Ref Is such the fast that I have chosen? the day for a man to afflict his soul? Is it to bow down his head as a rush, and to spread sackcloth and ashes under him? will you call this a fast, and an acceptable day to Yahweh?
6 Ref Isn't this the fast that I have chosen: to loose the bonds of wickedness, to undo the bands of the yoke, and to let the oppressed go free, and that you break every yoke?
