Acts 15:4

And this they did, sending it in charge of Barnabas and Saul to the elders.

And when they had arrived and gathered the church together, they began to report all things that God had done with them and how He had opened a door of faith to the Gentiles.

And when Paul and Barnabas had not a little dissension and debate with them, the brothers determined that Paul and Barnabas and some others of them should go up to Jerusalem to the apostles and elders concerning this issue.

Therefore, being sent on their way by the church, they were passing through both Phoenicia and Samaria, recounting in detail the conversion of the Gentiles, and were bringing great joy to all the brothers.

Both the apostles and the elders came together to look into this matter.

And all the multitude kept silent, and they were listening to Barnabas and Paul as they were relating what signs and wonders God had done through them among the Gentiles.

Was any man called when he was already circumcised? He is not to become uncircumcised. Has anyone been called in uncircumcision? He is not to be circumcised.
