Psalms 35:13

13 But as for me, when they were sick, my clothing was sackcloth: I humbled my soul with fasting; and my prayer returned into mine own bosom.

Psalms 69:10

10 When I wept, and chastened my soul with fasting, that was to my reproach.

Psalms 109:24

24 My knees are weak through fasting; and my flesh faileth of fatness.
