Esias 58:3

3 saying, Why have we fasted, and thou regardest not? have we afflicted our souls, and thou didst not know it? Nay, in the days of your fasts ye find your pleasures, and all them that are under your power ye wound.

Esias 58:3 In-Context

1 Cry aloud, and spare not; lift up thy voice as with a trumpet, and declare to my people their sins, and to the house of Jacob their iniquities.
2 They seek me day by day, and desire to know my ways, as a people that had done righteousness, and had not forsaken the judgment of their God: they now ask of me righteous judgment, and desire to draw nigh to God,
3 saying, Why have we fasted, and thou regardest not? have we afflicted our souls, and thou didst not know it? Nay, in the days of your fasts ye find your pleasures, and all them that are under your power ye wound.
4 If ye fast for quarrels and strifes, and smite the lowly with fists, wherefore do ye fast to me as this day, so that your voice may be heard in crying?
5 I have not chosen this fast, nor a day for a man to afflict his soul; neither though thou shouldest bend down thy neck as a ring, and spread under thee sackcloth and ashes, neither thus shall ye call a fast acceptable.
