For several days [Saul] was with the disciples in Damascus, and immediately he began to proclaim Jesus in the synagogues, saying, ‘He is the Son of God.’ All who heard him were amazed and said, ‘Is not this the man who made havoc in Jerusalem among those who invoked this name? And has he not come here for the purpose of bringing them bound before the chief priests?’ Saul became increasingly more powerful and confounded the Jews who lived in Damascus by proving that Jesus was the Messiah. After some time had passed, the Jews plotted to kill him, but their plot became known to Saul. They were watching the gates day and night so that they might kill him; but his disciples took him by night and let him down through an opening in the wall, lowering him in a basket. Acts 9:19-25 

…

When [Saul] had come to Jerusalem, he attempted to join the disciples; and they were all afraid of him, for they did not believe that he was a disciple.But Barnabas took him, brought him to the apostles, and described for them how on the road he had seen the Lord, who had spoken to him, and how in Damascus he had spoken boldly in the name of Jesus. So he went in and out among them in Jerusalem, speaking boldly in the name of the Lord. He spoke and argued with the Hellenists; but they were attempting to kill him. When the believers learned of it, they brought him down to Caesarea and sent him off to Tarsus. Meanwhile the church throughout Judea, Galilee, and Samaria had peace and was built up. Living in the fear of the Lord and in the comfort of the Holy Spirit, it increased in numbers. Acts 9:26-31
