Isaiah 40:3-5

King James Version

³ The voice of him that crieth in the wilderness, Prepare ye the way of the Lord, make straight in the desert a highway for our God.

⁴ 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:

⁵ And the glory of the Lord shall be revealed, and all flesh shall see it together: for the mouth of the Lord hath spoken it.
