As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
Said before - when visiting you (so "before" means, 2 Corinthians 13:2: cf. Galatians 5:2-3; Galatians 5:21), 'If any man preacheth х euangelizetai (G2097)] unto you any gospel,' etc.: the indicative, not the subjunctive or conditional mood, is used. The fact is assumed, not supposed as a contingency, as in Galatians 1:8, 'should preach.' This implies he had already observed (namely, during his last visit) the machinations of Judaizing teachers; but his surprise (Galatians 1:6) now at the Galatians being misled by them, implies that they had not apparently been so then. As in Galatians 1:8, he said, 'which we preached,' so here, with an augmentation of force, 'which ye received'-acknowledging that they had accepted it х parelabete (G3880)].
Accursed - ( anathema (G331), devoted to death, Leviticus 27:28). The opposite appears, Galatians 6:10.
