“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?
Is it not to share your food with the hungry
and to provide the poor
wanderer with shelter -
when you see him naked, to clothe him,
and not to turn away from your own flesh and blood?
Then your light will break forth like the dawn...” (Isaiah 58:6-8)
