Acts 9:1-3

During those days, Saul, full of angry threats and rage, wanted to murder the disciples of the Lord Jesus. So he went to ask the high priest and requested a letter of authorization he could take to the Jewish leaders in Damascus, requesting their cooperation in finding and arresting any who were followers of the Way. Saul wanted to capture all of the believers he found, both men and women, and drag them as prisoners back to Jerusalem. So he obtained the authorization and left for Damascus. Just outside the city, a brilliant light flashing from heaven suddenly exploded all around him.
