Isaiah 40:6

3 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.

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.

7 The grass withereth, the flower fadeth, because the breath of Jehovah bloweth upon it; surely the people is grass.

8 The grass withereth, the flower fadeth; but the word of our God shall stand forever.

9 O thou that tellest good tidings to Zion, get thee up on a high mountain; O thou that tellest good tidings to Jerusalem, lift up thy voice with strength; lift it up, be not afraid; say unto the cities of Judah, Behold, your God!
