Isaiah 40:3-5

Revised Standard Version Catholic Edition

³ A voice cries:
“In the wilderness prepare the way of the Lord,
    make straight in the desert a highway for our God.
⁴ Every valley shall be lifted up,
    and every mountain and hill be made low;
the uneven ground shall become level,
    and the rough places a plain.
⁵ And the glory of the Lord shall be revealed,
    and all flesh shall see it together,
    for the mouth of the Lord has spoken.”
