A.T. Robertson Commentary Acts 22:23

"And as they cried out, and threw off their garments, and cast dust into the air," — Acts 22:23 (ASV)

As they cried out (κραυγαζοντων αυτων). Genitive absolute with present active participle of κραυγαζω, a rare word in the old Greek from κραυγη (a cry). See on Mt 12:19. Two other genitive absolutes here, ριπτουντων (throwing off, present active participle, frequent active variation of ριπτω) and βαλλοντων (present active participle of βαλλω, flinging). These present participles give a lively picture of the uncontrolled excitement of the mob in their spasm of wild rage.
