Gevurot Meyruach Hakodesh 11:21-26

The hand of Adonoi was on them and a large number, having had emunah, turned to Moshiach Adoneinu. The report about them was heard in the ears of the Kehillah of Moshiach in Yerushalayim, and they sent out Bar-Nabba to go to Antioch; Who, having come, and having seen the Chen v'Chesed HASHEM, rejoiced and was encouraging everyone with deveykus (devotion) to HaAdon to remain true to Rebbe, Melech HaMoshiach Adoneinu. For Bar-Nabba was a mentsh, a gavra, an ish tov full of the Ruach Hakodesh and of emunah. And a great multitude was added to Adoneinu. And Bar-Nabba left for Tarsus to look for Sha'ul, And, having found him, he brought him to Antioch. And it came about that for an entire year, they met with Moshiachʼs Kehillah there, and taught a large multitude. And it was in Antioch that the talmidim were first called Ma'aminim HaMeshichiyim (Messianic Believers).
