1But certain persons came down from Judea, and began to teach the Lord's followers that, unless they were circumcised, in accordance with the custom required by Moses, they could not be saved.
2This gave rise to a serious dispute, and much discussion, between Paul and Barnabas and these people, and it was therefore settled that Paul and Barnabas and others of their number should go up to Jerusalem, to consult the apostles and church elders about the matter under discussion.
