Isaiah 40:3-8

The voice of one that crieth, Prepare ye in the wilderness the way of Jehovah; make level in the desert a highway for our God. 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: and the glory of Jehovah shall be revealed, and all flesh shall see it together; for the mouth of Jehovah hath spoken it. 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. The grass withereth, the flower fadeth, because the breath of Jehovah bloweth upon it; surely the people is grass. The grass withereth, the flower fadeth; but the word of our God shall stand forever.
