Acts 15:1-2

1And certain persons, having come down from Judaea, taught the brethren, If ye shall not have been circumcised according to the custom of Moses, ye cannot be saved.

2A commotion therefore having taken place, and no small discussion on the part of Paul and Barnabas against them, they arranged that Paul and Barnabas, and certain others from amongst them, should go up to Jerusalem to the apostles and elders about this question.
