Isaías 58:3-6 - Bíblia Online

'Why have we fasted,' they say, 'and you have not seen it? Why have we humbled ourselves, and you have not noticed?' "Yet on the day of your fasting, you do as you please and exploit all your workers. 
Your fasting ends in quarreling and strife, and in striking each other with wicked fists. You cannot fast as you do today and expect your voice to be heard on high. 
Is this the kind of fast I have chosen, only a day for people to humble themselves? Is it only for bowing one's head like a reed and for lying in sackcloth and ashes? Is that what you call a fast, a day acceptable to the LORD? 
"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?
