We do not dare to classify or compare ourselves with some who commend themselves. When they measure themselves by themselves and compare themselves with themselves, they show their ignorance.
KJV
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.
ASV
For we are not bold to number or compare ourselves with certain of them that commend themselves: but they themselves, measuring themselves by themselves, and comparing themselves with themselves, are without understanding.
