The joyful flourishing of Christ's kingdom, 1, 2. The weak are encouraged by the virtues and privileges of the Gospel, 3-10.
1  The wilderness and the solitary place shall be glad for them,/ 
and the desert shall rejoice and blossom like the rose.
2  It shall blossom abundantly and rejoice,/ 
even with joy and singing./ 
The glory of Lebanon shall be given to it,/ 
the excellence of Carmel and Sharon./ 
They shall see the glory of the LORD/ 
and the excellence of our God.
3  Strengthen the weak hands/ 
and confirm the feeble knees.
4  Say to those who are of a fearful heart,/ 
"Be strong. Do not fear./ 
Behold, your God will come with vengeance,/ 
even God with a recompense./ 
He will come and save you."
5  Then the eyes of the blind shall be opened/ 
and the ears of the deaf shall be unstopped.
6  Then the lame man shall leap like a buck,/ 
and the tongue of the mute shall sing./ 
For in the wilderness waters shall break out,/ 
and streams in the desert.
7  And the parched ground shall become a pool,/ 
and the thirsty land springs of water./ 
In the habitation of jackals, where each lay,/ 
there shall be grass with reeds and rushes.
8  And a highway shall be there, a road,/ 
and it shall be called, The Way of Holiness./ 
The unclean shall not pass over it,/ 
but it shall be for those who are way-faring men./ 
And fools shall not err therein.
9  No lion shall be there,/ 
nor any ravenous beast shall go up thereon./ 
It shall not be found there,/ 
but the redeemed shall walk there.
10 And the ransomed of the LORD shall return/ 
and come to Zion with songs/ 
and everlasting joy upon their heads./ 
They shall obtain joy and gladness,/ 
and sorrow and sighing shall flee away.
