Then Saul, still breathing threats and murder against the disciples of the Lord, went to the high priest 2 and asked letters from him to the synagogues of Damascus, so that if he found any who were of the Way, whether men or women, he might bring them bound to Jerusalem.
3 As he journeyed he came near Damascus, and suddenly a light shone around him from heaven. 4 Then he fell to the ground, and heard a voice saying to him, “Saul, Saul, why are you persecuting Me?”
5 And he said, “Who are You, Lord?”
Then the Lord said, “I am Jesus, whom you are persecuting. It is hard for you to kick against the goads.”
6 So he, trembling and astonished, said, “Lord, what do You want me to do?”
Then the Lord said to him, “Arise and go into the city, and you will be told what you must do.”
7 And the men who journeyed with him stood speechless, hearing a voice but seeing no one. 8 Then Saul arose from the ground, and when his eyes were opened he saw no one. But they led him by the hand and brought him into Damascus. 9 And he was three days without sight, and neither ate nor drank. — Acts 9:1-9.
On the Damascus Road, he is stopped by a bright light from heaven. Jesus reveals Himself to Saul and tells him to go into the city. He blinds Saul for three days. Saul, no doubt in shock as well as under conviction, neither eats nor drinks for three days.
