Isaiah 58:1-8

Cry aloud, spare not, lift up thy voice like a trumpet, and declare unto my people their transgression, and to the house of Jacob their sins. Yet they seek me daily, and delight to know my ways: as a nation that did righteousness, and forsook not the ordinance of their God, they ask of me righteous judgments; they delight to draw near unto God. Wherefore have we fasted, say they, and thou seest not? wherefore have we afflicted our soul, and thou takest no knowledge? Behold, in the day of your fast ye find your own pleasure, and exact all your labors. Behold, ye fast for strife and contention, and to smite with the fist of wickedness: ye fast not this day so as to make your voice to be heard on high. Is such the fast that I have chosen? the day for a man to afflict his soul? Is it to bow down his head as a rush, and to spread sackcloth and ashes under him? wilt thou call this a fast, and an acceptable day to Jehovah? Is not this the fast that I have chosen: to loose the bonds of wickedness, to undo the bands of the yoke, and to let the oppressed go free, and that ye break every yoke? Is it not to deal thy bread to the hungry, and that thou bring the poor that are cast out to thy house? when thou seest the naked, that thou cover him; and that thou hide not thyself from thine own flesh? Then shall thy light break forth as the morning, and thy healing shall spring forth speedily; and thy righteousness shall go before thee; the glory of Jehovah shall be thy rearward.
