15 I will lay waste the mountains and hills,
And dry up all their vegetation;
I will make the rivers coastlands,
And I will dry up the pools.

16 I will bring the blind by a way they did not know;
I will lead them in paths they have not known.
I will make darkness light before them,
And crooked places straight.
These things I will do for them,
And not forsake them.

18 “Hear, you deaf;
And look, you blind, that you may see.

19 ^aWho is blind but My servant,
Or deaf as My messenger whom I send?
Who is blind as he who is perfect,
And blind as the Lord’s servant? ‡
