³ A voice cries out:
    ‘In the wilderness prepare the way for the Lord;
        and^[a] in the desert a straight highway for our God.’
⁴ Every valley will be lifted up,
    and every mountain and hill will be lowered;
the rough ground will become level,
    and the mountain ridges made a plain.
⁵ Then the glory of the Lord will be revealed,
    and all humanity will see it at once;
        for the mouth of the Lord has spoken.”
