For this is he who was spoken of by Isaiah the prophet, saying,"The voice of one crying in the wilderness,make ready the way of the Lord.Make his paths straight."Isaiah 40:3

And you, child, will be called a prophet of the Most High,for you will go before the face of the Lord to prepare his ways,

He said, "I am the voice of one crying in the wilderness, 'Make straight the way of the Lord,' as Isaiah the prophet said."Isaiah 40:3
