And they that were with me saw indeed the light
 For it shone about them, as well as Saul: 
 and were afraid;
 the Alexandrian copy, the Vulgate Latin, and Syriac versions, have not this clause; but it stands in the Arabic and Ethiopic versions; the suddenness, greatness, and extraordinariness of the light surprised them, for it was even miraculous: 
 but they heard not the voice of him that spake to me:
 they heard the voice of Saul, but not the voice of Christ; at least they did not hear it so as to understand it; (See Gill on Acts 9:7).
