Acts 9:26-29

26 On reaching Yerushalayim, he tried to join the talmidim; but they were all afraid of him - they didn't believe he was a talmid.

27 However, Bar-Nabba got hold of him and took him to the emissaries. He told them how Sha'ul had seen the Lord while traveling, that the Lord had spoken to him, and how in Dammesek Sha'ul had spoken out boldly in the name of Yeshua.

28 So he remained with them and went all over Yerushalayim continuing to speak out boldly in the name of the Lord.

29 He talked and debated with the Greek-speaking Jews, but they began making attempts to kill him.
