Isaiah 40:6

4 Every valley shall be lifted up, and every mountain and hill made low; the uneven ground will become smooth, and the rugged land a plain.

5 And the glory of the LORD will be revealed, and all humanity together will see it. For the mouth of the LORD has spoken.”

A voice says, “Cry out!” And I asked, “What should I cry out?” “All flesh is like grass, and all its glory like the flowers of the field.

7 The grass withers and the flowers fall when the breath of the LORD blows on them; indeed, the people are grass.

8 The grass withers and the flowers fall, but the word of our God stands forever.”

Do read the surrounding verses too, because the context often says more than a single verse.
