Isaiah 40:3-5New Revised Standard Version (NRSV)
3 A voice cries out:
“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 Then the glory of the Lord shall be revealed,
and all people shall see it together,
for the mouth of the Lord has spoken.”
