Adam Clarke on Luke 8:28

Jesus, thou Son of God most high - The words Jesus and God are both omitted here by several MSS. I think it is very likely that the demons mentioned neither. They were constrained in a summary way to acknowledge his power; but it is probable they did not pronounce names which were of such dreadful import to themselves. The words which they spoke on the occasion seem to have been these, What is it to thee and me, O Son of the most high? See the note on Mat 8:29.
