Isaiah 42:7

New English Translation

⁷to open blind eyes,^[a]
to release prisoners^[b] from dungeons,
those who live in darkness from prisons.

Isaiah 42:7 sn This does not refer to literal physical healing of the blind. As the next two lines suggest, this refers metonymically to freeing captives from their dark prisons where their eyes have grown unaccustomed to light.
Isaiah 42:7 sn This does not refer to hardened, dangerous criminals, who would have been executed for their crimes in ancient Near Eastern society. This verse refers to political prisoners or victims of social injustice.
