15. Where, &c.--Of what value was your congratulation (so the Greek for "blessedness" expresses) of yourselves, on account of your having among you me, the messenger of the Gospel, considering how entirely you have veered about since? Once you counted yourselves blessed in being favored with my ministry.
      ye would have plucked out your own eyes--one of the dearest members of the body--so highly did you value me: a proverbial phrase for the greatest self-sacrifice (Mt 5:29). CONYBEARE and HOWSON think that this particular form of proverb was used with reference to a weakness in Paul's eyes, connected with a nervous frame, perhaps affected by the brightness of the vision described, Ac 22:11; 2Co 12:1-7. "You would have torn out your own eyes to supply the lack of mine." The divine power of Paul's words and works, contrasting with the feebleness of his person (2Co 10:10), powerfully at first impressed the Galatians, who had all the impulsiveness of the Celtic race from which they sprang. Subsequently they soon changed with the fickleness which is equally characteristic of Celts.
