Galatians 2:8-9

(for he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:) and when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision.
