Isaiah 40:4-6

New Catholic Bible

⁴ Let every valley be filled in
    and every mountain and hill be made low.
Uneven ground will be made smooth
    and the rugged places will become a plain.
⁵ Then the glory of the Lord will be revealed,
    and all mankind will see it together,
    for the mouth of the Lord has spoken.
⁶ A voice says, “Cry out!”
    I reply, “What shall I cry out?”
“All mortals are grass;
    they last no longer than the flowers of the field.
