Isaiah 40:3-4

Amplified Bible

³ 
A voice of one is calling out,
“Clear the way for the Lord in the wilderness [remove the obstacles];
Make straight and smooth in the desert a highway for our God.^(A)
4 
“Every valley shall be raised,
And every mountain and hill be made low;
And let the rough ground become a plain,
And the rugged places a broad valley.
