Isaiah 38:3 (NLT)
3“Remember, O Lord, how I have always been faithful to you and have served you single-mindedly, always doing what pleases you.” Then he broke down and wept bitterly.
Isaiah 58:5 (NLT)
5You humble yourselves by going through the motions of penance, bowing your heads like reeds bending in the wind. You dress in burlap and cover yourselves with ashes. Is this what you call fasting? Do you really think this will please the Lord?
