2 Samuel 12:23
But now he is dead, why should I fast? can I bring him back again? I shall go to him, but he will not return to me.
Wherefore have we fasted, and thou seest not; have afflicted our soul, and thou takest no knowledge? Behold, in the day of your fast ye find what pleaseth you, and exact all your labours.
Behold, ye have fasted for strife and debate, and to smite with the fist of wickedness; ye do not at present fast, to cause your voice to be heard on high.
When they fast, I will not hear their cry; and when they offer up burnt-offering and oblation, I will not accept them: for I will consume them by sword, and by famine, and by pestilence.
