Galatians 2:2-4

Amplified Bible

² I 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 ^[a]reputation, for fear that I might be running or had run [the course of my ministry] in vain. ³ But [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. ⁴ My concern was because of the ^[b]false brothers [those people masquerading as Christians] who had been secretly smuggled in [to the community of believers]. They had slipped in to spy on the freedom which we have in Christ Jesus, in order to bring us back into bondage [under the Law of Moses].
