Galatians 2:2-6

2And I went up by revelation, and communicated to them that gospel which I preach among the Gentiles, but privately to those who were of reputation, lest by any means I might run, or had run, in vain.

3Yet not even Titus who was with me, being a Greek, was compelled to be circumcised.

4And this occurred because of false brethren secretly brought in (who came in by stealth to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage),

5to whom we did not yield submission even for an hour, that the truth of the gospel might continue with you.

6But from those who seemed to be something—whatever they were, it makes no difference to me; God shows personal favoritism to no man—for those who seemed to be something added nothing to me.
