ACC ~ Galatians 2 v2a

WHY “BY REVELATION”? CHRYSOSTOM: The purpose for his saying “through revelation” was that even before the solution to the question [why he spoke of running in vain] no one should accuse him of any ignorance, knowing that what occurred was not of human origin but of a certain divine dispensation which had in view many things, both present and to come. What then is the reason for this journey? When he first went up from Antioch to Jerusalem it was not for his own sake, for he himself knew that he ought to follow strictly the teachings of Christ. Rather he wanted to win over those who opposed him. He himself had no need at this point to ascertain whether he ran in vain, but [he went up] to satisfy his detractors. HOMILY ON GALATIANS 2.2.
