Isaiah 58:4-7

What good is fasting when you keep on fighting and quarreling? This kind of fasting will never get you anywhere with me. You humble yourselves by going through the motions of penance, bowing your heads like reeds bending in the wind. You dress in burlap and cover yourselves with ashes. Is this what you call fasting? Do you really think this will please the LORD? “No, this is the kind of fasting I want: Free those who are wrongly imprisoned; lighten the burden of those who work for you. Let the oppressed go free, and remove the chains that bind people. Share your food with the hungry, and give shelter to the homeless. Give clothes to those who need them, and do not hide from relatives who need your help.
