KJV

And I will bring the blind by a way that they knew not; I will lead them in paths that they have not known: I will make darkness light before them, and crooked things straight. These things will I do unto them, and not forsake them.

EEV (modified)

As the LORD told the Children of Israel, He tells us. He will lead us, who are physically and figuratively blind, by ways that we haven't known. He will be our guide along paths that are new to us. He will make the dark places in front of us into light places. And He will make the rough places flat. Those are things that God said that He will do. He promises that He will not leave His people - us by ourselves.
