Every valley shall be exalted, and every mountain and hill shall be made low: and the crooked shall be made straight, and the rough places plain 

— Isaiah 40:4, King James Bible

I have a dream that one day every valley shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.

— Martin Luther King, Jr., I Have A Dream Speech
