Isaiah 40:6-8

New Revised Standard Version Catholic Edition

⁶ A voice says, “Cry out!”
    And I said, “What shall I cry?”
All people are grass,
    their constancy is like the flower of the field.
⁷ The grass withers, the flower fades,
    when the breath of the Lord blows upon it;
    surely the people are grass.
⁸ The grass withers, the flower fades;
    but the word of our God will stand forever.
