Isaiah 58:1-4

1Cry aloud, spare not, lift up thy voice like a trumpet, and show my people their transgression, and the house of Jacob their sins.1 2Yet 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 the ordinances of justice; they take delight in approaching to God.

3Why have we fasted, say they, and thou seest not? why have we afflicted our soul, and thou takest no knowledge? Behold, in the day of your fast ye find pleasure, and exact all your labours.2 4Behold, ye fast for strife and debate, and to smite with the fist of wickedness: ye shall not fast as ye do this day, to make your voice to be heard on high.3
