Acts 15:2
After Paul and Barnabas had a heated debate and argued with these men [over this issue], the brothers [of the Antioch church] decided that Paul and Barnabas, along with certain others, should go up to Jerusalem and discuss the question with the apostles and elders there.
Galatians 2:2
[It was] in response to [a divine] revelation that I went [there] and explained to them [I. e., the apostles and elders] the Gospel [message] that I had been preaching among the Gentiles. Then [later on I presented it] privately before those who were highly regarded [i.e., the three apostles, verse 9] so [they would have verification that] my running [i.e., ministry] had not been, nor was now, in vain.
Philippians 1:24-25
Yet [on the other hand], to remain in my body is more necessary for your sakes.
