A.T. Robertson Commentary Acts 9:8

"And Saul arose from the earth; and when his eyes were opened, he saw nothing; and they led him by the hand, and brought him into Damascus." — Acts 9:8 (ASV)

He saw nothing (ουδεν εβλεπεν). Imperfect active indicative, was seeing nothing. "The glory of that light" (22:11) when he saw Jesus had blinded his eyes now wide open (ανεωιγμενων, perfect passive participle of ανοιγω with double reduplication). The blindness was proof that something had happened to him and that it was no hallucination that he had seen the Risen Christ. Saul arose after the others were on their feet.

They led him by the hand (χειραγωγουντες). From χειραγωγος (χειρ, hand and αγω, to lead). Only here in the N.T., but in LXX and late writers though not in the old Greek. It was a pathetic picture to see the masterful Saul, victorious persecutor and conqueror of the disciples, now helpless as a child.
