Galatians 2:2-3

2I went there because God revealed to me that I should go. While I was there I met privately with those considered to be leaders of the church and shared with them the message I had been preaching to the Gentiles. I wanted to make sure that we were in agreement, for fear that all my efforts had been wasted and I was running the race for nothing.

3And they supported me and did not even demand that my companion Titus be circumcised, though he was a Gentile.
