Of such an one will I glory: yet of myself I will not glory, but in mine infirmities.
Of myself - concerning myself. Self is put in the background, except his infirmities. His glorying in his other self, to which the revelations were vouchsafed, was not to give glory to his fleshly self, but to bring out in contrast the 'infirmities" of the latter, that Christ might have all the glory.
