Galatians 2:2-3

2I went up [to Jerusalem] because of a [divine] revelation, and I put before them the gospel which I preach among the Gentiles. But I did so in private before those of reputation, for fear that I might be running or had run [the course of my ministry] in vain.

3But [all went well, for] not even Titus, who was with me, was compelled [as some had anticipated] to be circumcised, despite the fact that he was a Greek.
