Acts 9:26-28
Saul Returns to Jerusalem
9:26 When he arrived in Jerusalem, he attempted to associate with the disciples, and they were all afraid of him, because they did not believe that he was a disciple.
9:27 But Barnabas took Saul, brought him to the apostles, and related to them how he had seen the Lord on the road, that the Lord had spoken to him, and how in Damascus he had spoken out boldly in the name of Jesus.
9:28 So he was staying with them, associating openly with them in Jerusalem, speaking out boldly in the name of the Lord.
Galatians 1:18
1:18 Then after three years I went up to Jerusalem to visit Cephas and get information from him, and I stayed with him fifteen days.
