Galatians 2:13

The other Jews... — i.e. converts from Judaism, as distinct from Gentile converts, in the Church at Antioch.

Dissembled. — The “dissimulation,” or “hypocrisy” (the literal sense of the Greek word), consisted in suppressing their real convictions, and acting as if from a set of convictions different from their real ones.

Barnabas also. — Rather, even Barnabas, my own familiar friend, and so recently my ally in pleading the cause of the Gentiles. The beginning of the breach which soon afterwards led to the definite separation of the two Apostles would seem to be traceable here.
