Galatians 2:1-3
Confirmation from the Jerusalem Apostles
2:1 Then after fourteen years I went up to Jerusalem again with Barnabas, taking Titus along too.
2:2 I went there because of a revelation and presented to them the gospel that I preach among the Gentiles. But I did so only in a private meeting with the influential people, to make sure that I was not running – or had not run – in vain.
2:3 Yet not even Titus, who was with me, was compelled to be circumcised, although he was a Greek.
