Acts 22:6-9
"On that journey as I drew near to Damascus, about noon a great light from the sky suddenly shone around me. I fell to the ground and heard a voice saying to me, 'Saul, Saul, why are you persecuting me?' I replied, 'Who are you, sir?' And he said to me, 'I am Jesus the Nazorean whom you are persecuting.' My companions saw the light but did not hear the voice of the one who spoke to me.
