Gal 2:5 to whom not ['οὐδὲ'] for an hour we gave place by subjection, that the truth of the good news might remain to you.
According to http://www.laparola.net/greco/index.php:
οἷς without οὐδὲ appears in very few witnesses (all of the them late) compared with οἷς οὐδὲ (notice p46).
About p46, it reads (according to Laparola):
Gal 2:12 for before the coming of certain from James, with the gentiles he was eating, and when he [instead of "they"] came, he was withdrawing and separating himself, fearing those of the circumcision,
p46 allows: Peter could have known about certain from James in Antioch and what he was preaching, either before Peter reached that city or when he got into Antioch, and immediatly changed his way towards gentiles.
"Esteemed pillars" vis a vis "men from James": Re-imagining the context for the way Paul spoke to Peter "to his face."
