Gevurot 15:1-3

Orthodox Jewish Bible

15 And some men came down from Yehudah to Syrian Antioch and were teaching the Achim b’Moshiach that if you lack the bris milah as prescribed by Moshe Rabbenu, it is impossible for you to come to Yeshu’at Eloheinu.

² Now this brought them into a dispute and a debate of no little proportion with Rav Sha’ul and Bar-Nabba, who were appointed to go up with some others from them to bring this she’elah (question) before the Moshiach’s Shlichim and Zekenim in Yerushalayim.

³ Then having been sent on their way by the Kehillah, they were passing through both Phoenicia and Shomron telling in detail how the Nations were turning to Hashem and they were bringing great simcha to all the Achim b’Moshiach.
