Isaiah 42:6-7
"I, the LORD, have called you in righteousness;
I will take hold of your hand.
I will keep you and will make you
to be...a light for the Gentiles, 
to open eyes that are blind,
to free captives from prison
and to release from the dungeon those who sit in darkness.

Isaiah 61:1-4
The Spirit of the Sovereign LORD is on me,
because the LORD has anointed me
to preach good news to the poor.
He has sent me to bind up the brokenhearted,
to proclaim freedom for the captives
and release from darkness for the prisoners,   
to proclaim the year of the LORD's favor
and the day of vengeance of our God,
to comfort all who mourn, 
and provide for those who grieve in Zion--
to bestow on them a crown of beauty
instead of ashes,
the oil of gladness
instead of mourning,
and a garment of praise
instead of a spirit of despair.
They will be called oaks of righteousness,
a planting of the LORD
for the display of his splendor.
They will rebuild the ancient ruins
and restore the places long devastated;
they will renew the ruined cities
that have been devastated for generations.
