[4] But because of false brethren unawares brought in, who came in privately to spy our liberty, which we have in Christ Jesus, that they might bring us into servitude. [5] To whom we yielded not by subjection, no not for an hour, that the truth of the gospel might continue with you. [6] But of them who seemed to be some thing, (what they were some time, it is nothing to me, God accepteth not the person of man,) for to me they that seemed to be some thing added nothing.

[8] (For he who wrought in Peter to the apostleship of the circumcision, wrought in me also among the Gentiles.) [9] And when they had known the grace that was given to me, James and Cephas and John, who seemed to be pillars, gave to me and Barnabas the right hands of fellowship: that we should go unto the Gentiles, and they unto the circumcision
