For we dare not make ourselves of the number, or compare ourselves with some that commend themselves: but they measuring themselves by themselves, and comparing themselves among themselves, are not wise. We dare not make ourselves, etc. - As if he had said: I dare neither associate with, nor compare myself to, those who are full of self-commendation. Some think this to be an ironical speech.
But they, measuring themselves by themselves - They are not sent of God; they are not inspired by his Spirit; therefore they have no rule to think or act by. They are also full of pride and self-conceit; they look within themselves for accomplishments which their self-love will soon find out; for to it real and fictitious are the same. As they dare not compare themselves with the true apostles of Christ, they compare themselves with each other; and, as they have no perfect standard, they can have no excellence; nor can they ever attain true wisdom, which is not to be had from looking at what we are but to what we should be; and if without a directory, what we should be will never appear, and consequently our ignorance must continue. This was the case with these self-conceited false apostles; but ου συνιουσιν, are not wise, Mr. Wakefield contends, is an elegant Graecism signifying they are not aware that they are measuring themselves by themselves, etc.
