But Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest and asked him for letters to the synagogues at Damascus, so that if he found any belonging to the Way, men or women, he might bring them bound to Jerusalem. Now as he went on his way, he approached Damascus, and suddenly a light from heaven shone around him. And falling to the ground, he heard a voice saying to him, "Saul, Saul, why are you persecuting me?" And he said, "Who are you, Lord?" And he said, "I am Jesus, whom you are persecuting. But rise and enter the city, and you will be told what you are to do." The men who were traveling with him stood speechless, hearing the voice but seeing no one. Saul rose from the ground, and although his eyes were opened, he saw nothing. So they led him by the hand and brought him into Damascus. And for three days he was without sight, and neither ate nor drank.
