A.T. Robertson Commentary Acts 22:8

"And I answered, Who art thou, Lord? And he said unto me, I am Jesus of Nazareth, whom thou persecutest." — Acts 22:8 (ASV)

Of Nazareth (ο Ναζωραιος). The Nazarene, not in 9:5; 26:15 and here because Jesus is mentioned now for the first time in the address. The form Ναζωραιος as in Mt 2:23 (which see) is used also in 24:5 for the followers of Jesus instead of Ναζαρηνος as in Mr 1:24, etc. (which see).
