Isaiah 37:3

37:3 “This is what Hezekiah says: ‘This is a day of distress, insults, and humiliation, as when a baby is ready to leave the birth canal, but the mother lacks the strength to push it through.

Isaiah 58:5

58:5 Is this really the kind of fasting I want?

Do I want a day when people merely humble themselves,

bowing their heads like a reed

and stretching out on sackcloth and ashes?

Is this really what you call a fast,

a day that is pleasing to the Lord?
