Galatians 2:7-13 AMP

7 But on the contrary, when they [really] saw that I had been entrusted [to carry] the Gospel to the uncircumcised [Gentiles, just as definitely] as Peter had been entrusted [to proclaim] the Gospel to the circumcised [Jews, they were agreeable];

8 For He Who motivated and fitted Peter and worked effectively through him for the mission to the circumcised, motivated and fitted me and worked through me also for [the mission to] the Gentiles.

9 And when they knew (perceived, recognized, understood, and acknowledged) the grace (God's unmerited favor and spiritual blessing) that had been bestowed upon me, James and Cephas (Peter) and John, who were reputed to be pillars of the Jerusalem church, gave to me and Barnabas the right hand of fellowship, with the understanding that we should go to the Gentiles and they to the circumcised (Jews).

10 They only [made one stipulation], that we were to remember the poor, which very thing I was also eager to do.

11 But when Cephas (Peter) came to Antioch, I protested and opposed him to his face [concerning his conduct there], for he was blameable and stood condemned.

12 For up to the time that certain persons came from James, he ate his meals with the Gentile [converts]; but when the men [from Jerusalem] arrived, he withdrew and held himself aloof from the Gentiles and [ate] separately for fear of those of the circumcision [party].

13 And the rest of the Jews along with him also concealed their true convictions and acted insincerely, with the result that even Barnabas was carried away by their hypocrisy (their example of insincerity and pretense).
