6 "Is not this the kind of fasting I have chosen:
       to loose the chains of injustice
       and untie the cords of the yoke,
       to set the oppressed free
       and break every yoke? ...

 8 Then your light will break forth like the dawn,
       and your healing will quickly appear;
       then your righteousness will go before you,
       and the glory of the LORD will be your rear guard.

Isaiah 58:6,8 NIV
