Listen! It’s the voice of someone shouting,
“Clear the way through the wilderness for the LORD!
Make a straight highway through the wasteland for our God!
Fill in the valleys,
and level the mountains and hills.
Straighten the curves,
and smooth out the rough places.
Then the glory of the LORD will be revealed,
and all people will see it together.
The LORD has spoken!”
Isaiah 40:3-5
