Seeing that many glory after the flesh, I will glory also.

People's New Testament

11:18 I will glory also. This is the folly for which he apologizes. He will show that he is not behind those who have been claiming so much credit at Corinth.

Wesley's Notes

11:18 After the flesh - That is, in external things.

Jamieson-Fausset-Brown Bible Commentary

18. many-including the "false teachers."

after the flesh-as fleshly men are wont to boast, namely, of external advantages, as their birth, doings, &c. (compare 2Co 11:22).

I will glory also-that is, I also will boast of such fleshly advantages, to show you that even in these I am not their inferiors, and therefore ought not to be supplanted by them in your esteem; though these are not what I desire to glory in (2Co 10:17).

Matthew Henry's Concise Commentary

11:16-21 It is the duty and practice of Christians to humble themselves, in obedience to the command and example of the Lord; yet prudence must direct in what it is needful to do things which we may do lawfully, even the speaking of what God has wrought for us, and in us, and by us. Doubtless here is reference to facts in which the character of the false apostles had been shown. It is astonishing to see how such men bring their followers into bondage, and how they take from them and insult them.
