Seeing that many glory after the flesh
Or with respect to things external, such as their high birth and parentage, carnal descent, circumcision, learned education, and the like; of which the false apostles, being Jews, boasted, who it seems were many; and though a multitude is not to be followed to do evil, yet the apostle thought, that since there were so many who were indulged by this church in this way, he might be allowed to boast also of such like things, so far as he could with truth and a good conscience, and in order to secure some valuable ends:
I will glory also;
for he was of the seed of Abraham as well as they, of the stock of Israel, and tribe of Benjamin, circumcised the eighth day, and brought up at the feet of Gamaliel; but these are not all the things he could, and would, and did glory of; he gloried of these, and of others besides them, which the false apostles could not, and thereby proved himself to be superior to them, even in external things, of which they bragged so much.
