Galatians 2:3-4

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

4Even 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.
