Saying, Let us alone; what have we to do with you, Jesus of Nazareth? are you come to destroy us? I know you, who you are, the Holy One of God.
All Commentaries on Mark 1:24 Go To Mark 1
Augustine of Hippo
AD 430
Unclean spirits knew that Jesus Christ would come. They had heard it from the angels, they had heard it from the prophets, so they were expecting him to come. For if not, why did they cry out, “What have we to do with you? Have you come to destroy us before the time? We know who you are, the holy one of God.” .
