Galatians 2:1-4

Then fourteen years later I went back to Jerusalem again, this time with Barnabas; and Titus came along, too. I 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. And they supported me and did not even demand that my companion Titus be circumcised, though he was a Gentile. Even that question came up only because of some so-called believers there—false ones, really—who were secretly brought in. They sneaked in to spy on us and take away the freedom we have in Christ Jesus. They wanted to enslave us and force us to follow their Jewish regulations.
