But contrariwise, when they saw; they were so far from contradicting any thing that I had preached, that when they understood from me, and Barnabas, \who Acts 15:12, declared in the council what miracles and wonders God had wrought among the Gentiles by them\ that the gospel of the uncircumcision, that the business of preaching the gospel to those who were no Jews, (for that is meant by uncircumcision; not simply those that were not circumcised, for some of the heathens were circumcised, yet all go in Scripture under the name of uncircumcised), was committed unto me, as the gospel of the circumcision was unto Peter; as the preaching of the gospel to the Jews was committed to Peter, and not to him only, but to James and John. It must not be so understood, as if Paul might not preach to the Jews, or Peter might not preach to the Gentiles, (for the contrary is evident from Acts 9:15, as to Paul, and from Peter's preaching to Cornelius, Acts 10:1-48), but because God designed the Gentiles to be more especially the province for Paul to exercise his ministry in, Acts 26:17, (and accordingly he was specially sent out by the church, Acts 13:3), as Peter's chief work was among the Jews.
