Revised Standard Version
4 Behold, you fast only to quarrel and to fight
and to hit with wicked fist.
Fasting like yours this day
will not make your voice to be heard on high.
5 Is such the fast that I choose,
a day for a man to humble himself?
Is it to bow down his head like a rush,
and to spread sackcloth and ashes under him?
Will you call this a fast,
and a day acceptable to the Lord?
6 “Is not this the fast that I choose:
to loose the bonds of wickedness,
to undo the thongs of the yoke,
to let the oppressed go free,
and to break every yoke?
