Then after fourteen years I went up again to Jerusalem with Barnabas, taking Titus along with me. I went up by revelation; and I laid before them (but privately before those who were of repute) the gospel which I preach among the Gentiles, lest somehow I should be running or had run in vain. But even Titus, who was with me, was not compelled to be circumcised, though he was a Greek. But because of false brethren secretly brought in, who slipped in to spy out our freedom which we have in Christ Jesus, that they might bring us into bondage— to them we did not yield submission even for a moment, that the truth of the gospel might be preserved for you. And from those who were reputed to be something (what they were makes no difference to me; God shows no partiality)—those, I say, who were of repute added nothing to me; but on the contrary, when they saw that I had been entrusted with the gospel to the uncircumcised, just as Peter had been entrusted with the gospel to the circumcised (for he who worked through Peter for the mission to the circumcised worked through me also for the Gentiles), and when they perceived the grace that was given to me, James and Cephas and John, who were reputed to be pillars, gave to me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised; only they would have us remember the poor, which very thing I was eager to do.
