Isaiah 50:2

50:2 Why does no one challenge me when I come?

Why does no one respond when I call?

Is my hand too weak to deliver you?

Do I lack the power to rescue you?

Look, with a mere shout I can dry up the sea;

I can turn streams into a desert,

so the fish rot away and die

from lack of water.

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?
