14 For a long time I have held my peace;
I have kept still and restrained myself;
now I will cry out like a woman in labor;
I will gasp and pant.
15 I will lay waste mountains and hills,
and dry up all their vegetation;
I will turn the rivers into islands, 
and dry up the pools.
16 And I will lead the blind
in a way that they do not know,
in paths that they have not known
I will guide them.
I will turn the darkness before them into light,
the rough places into level ground.
These are the things I do,
and I do not forsake them.
17 They are turned back and utterly put to shame,
who trust in carved idols,
who say to metal images,
“You are our gods.”
18 Hear, you deaf,
and look, you blind, that you may see!
19 Who is blind but my servant,
or deaf as my messenger whom I send?
Who is blind as my dedicated one, 
or blind as the servant of the Lord?
20 He sees many things, but does not observe them;
his ears are open, but he does not hear.
21 The Lord was pleased, for his righteousness' sake,
to magnify his law and make it glorious. (ESV)
