Passage
And when Peter came to Antioch, to the face I stood up against him, because he was blameworthy,
And when Peter came to Antioch, to the face I stood up against him, because he was blameworthy,
Galatians 2:9 and having known the grace that was given to me, James, and Cephas, and John, who were esteemed to be pillars, a right hand of fellowship they did give to me, and to Barnabas, that we to the nations, and they to the circumcision <FI>may go<Fi> ,
Galatians 2:10 only, of the poor that we should be mindful, which also I was diligent--this very thing--to do.
Galatians 2:11 And when Peter came to Antioch, to the face I stood up against him, because he was blameworthy,
Galatians 2:12 for before the coming of certain from James, with the nations he was eating, and when they came, he was withdrawing and separating himself, fearing those of the circumcision,
Galatians 2:13 and dissemble with him also did the other Jews, so that also Barnabas was carried away by their dissimulation.
The verse centers on "peter", "came", "antioch", "face", "stood", "against", and "blameworthy". It is saying that the verse draws attention to "peter" and "came", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "only of the poor that we should..." into verse 12's "for before the coming of certain from...", so "peter" and "came" belong inside that flow. In Galatians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "peter" and "came" with trust shaped by these words, not by a vague optimism outside the passage.
