Pseudo-Jerome
Catena Aurea · Markusevangelium 1
(Mal. 3:1) As it is written in the Prophets, Behold, I send my messenger before thy face, which shall prepare thy way before thee. The voice of one crying in the wilderness, (Isa. 40:3) Prepare ye the way of the Lord, make his paths straight.
Or else the voice and the cry is in the desert, because they were deserted by the Spirit of God, as a house empty, and swept out; deserted also by prophet, priest, and king.
