Mark 1:24

Let us alone Many MSS. omit the Greek word thus translated. Even if genuine, it appears to be rather an exclamation of horror = the Latin vah! heu!It is not the man who cries out so much as the Evil Spirit which had usurped dominion over him.

Jesus of Nazareth As the angels had in songs of rapture recognised their King (Luke 2:13-14), so the evil spirits instantly recognise Him, but with cries of despair. They evince no hope and no submission, only inveterate hostility. They believe and tremble(James 2:19). Man alone recognises not the "King in His beauty" (Isaiah 33:17). "He was in the world and the world was made by Him," and yet "the world knew Him not" (John 1:10).
