But I certify you, brethren ( γνωρίζω δὲ γνωρίζω γὰρ ὑμῖν ἀδελφοί) now (or, for) I make known unto you, brethren. The external evidence, as well as the judgment of critics, is so evenly divided between the two readings, γνωρίζω δὲ and γνωρίζω γάρ, that the decision as to which is to be preferred seems to lie with exegesis rather than with diplomatic criticism.
On the one hand, the fact that the gospel which the apostle had delivered to the Galatians came to him by a direct revelation from Christ, would be properly viewed as a reason for regarding it as sacred and inviolable.
Viewed thus, the reading, "now I make known to you," appears justified as introducing a plea warranting the anathema of verses 8, 9. On the other hand, there is a difference of tone perceptible between the previous context, which is strongly marked, as we have seen, by intense excitement of feeling, and the passage which commences with this verse.
