From the Book of Isaiah

"...Do you call this a fast,
a day acceptable to the LORD?
This, rather, is the fasting that I wish:
releasing those bound unjustly,
untying the thongs of the yoke;
Setting free the oppressed,
breaking every yoke;
Sharing your bread with the hungry,
sheltering the oppressed and the homeless;
Clothing the naked when you see them,
and not turning your back on your own.
Then your light shall break forth like the dawn,
and your wound shall quickly be healed..."
