Atos 9:7

(7) Hearing a voice, but seeing no man.—We are told by St. Paul himself (Acts 22:9) that they “did not hear the voice.” What is meant is clearly that they did not hear the words—could attach no meaning to the sounds which for Saul himself had so profound a significance. So, in like manner, they saw the light, but did not see the form. In Acts 26:14, they also are said to have fallen on the ground in terror.
