Acts 15:1-2

1Some men came down from Judea and began teaching the brothers, “Unless you are circumcised in accordance with the custom of Moses, you cannot be saved.”

2Paul and Barnabas disagreed greatly and debated with them, so it was determined that Paul and Barnabas and some of the others from their group would go up to Jerusalem to the apostles and the elders [and confer with them] concerning this issue.
