Albert Barnes Commentary Isaiah 29:18

"And in that day shall the deaf hear the words of the book, and the eyes of the blind shall see out of obscurity and out of darkness." — Isaiah 29:18 (ASV)

Shall the deaf hear the words of the book - They who now have the law and do not understand it, the people who seem to be deaf to all that God says, shall hear and understand it.

Shall see out of obscurity ... - That is, the darkness being removed, they shall see clearly the truth of God, and discern and love its beauty. Their eyes are now blinded, but then they shall see clearly.
