The voice of him that cries in the wilderness, Prepare you the way of the LORD, make straight in the desert a highway for our God.
All Commentaries on Isaiah 40:3 Go To Isaiah 40
Augustine of Hippo
AD 430
There it is written, “a voice of one crying in the wilderness,” the Word is conceived in the virgin’s womb. If the voice is not the Word, it is then a loud clanging of metal. For one then would not be able to say that every word is a sound but not every sound is a word. For it is not unfitting to take “the way” as that which came up to the very heart and filled us inwardly. Indeed, the heart became his place to which he comes and remains.
