5 Is such the fast that I choose,
a day for a person to humble himself?
Is it to bow down his head like a reed,
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 straps of the yoke,
to let the oppressed go free,
and to break every yoke?
7 Is it not to share your bread with the hungry
and bring the homeless poor into your house;
when you see the naked, to cover him,
and not to hide yourself from your own flesh?
8 Then shall your light break forth like the dawn,
and your healing shall spring up speedily;
your righteousness shall go before you;
the glory of the Lord shall be your rear guard.
9 Then you shall call, and the Lord will answer;
you shall cry, and he will say, ‘Here I am.’
If you take away the yoke from your midst,
the pointing of the finger, and speaking wickedness, (ESV)
