Isaiah 40:4-6

American Standard Version

⁴ Every valley shall be exalted, and every mountain and hill shall be made low; and the uneven shall be made level, and the rough places a plain: ⁵ and the glory of Jehovah shall be revealed, and all flesh shall see it together; for the mouth of Jehovah hath spoken it.

⁶ The voice of one saying, Cry. And one said, What shall I cry? All flesh is grass, and all the goodliness thereof is as the flower of the field.
