Acts 9:3-9

As he traveled he approached Damascus, and suddenly a light from heaven flashed around him [displaying the glory and majesty of Christ]; and he fell to the ground and heard a voice [from heaven] saying to him, “Saul, Saul, why are you persecuting and oppressing Me?” And Saul said, “Who are You, Lord?” And He answered, “I am Jesus whom you are persecuting, now get up and go into the city, and you will be told what you must do.” The men who were traveling with him [were terrified and] stood speechless, hearing the voice but seeing no one. Saul got up from the ground, but though his eyes were open, he could see nothing; so they led him by the hand and brought him into Damascus. And he was unable to see for three days, and he neither ate nor drank.
