Isaiah 30:21

“Those who err in spirit will know discernment, And those who criticize will gain learning.

And a roadway will be there, a highway, And it will be called the Highway of Holiness. The unclean will not pass by on it, But it will be for him who walks in that way, And ignorant fools will not wander on it.

“I will lead the blind by a way they do not know, In paths they do not know I will guide them. I will make darkness into light before them And rugged places into plains. These are the things I will do, And I will not forsake them.”

Thus says Yahweh, your Redeemer, the Holy One of Israel, “I am Yahweh your God, who teaches you to profit, Who leads you in the way you should go.
