Galatians 2:8-9

8(for He who worked effectively in Peter for the apostleship to the circumcised also worked effectively in me toward the Gentiles),

9and when James, Cephas, and John, who seemed to be pillars, perceived the grace that had been given to me, they gave me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised.
