2 Corinthians 10:12 in the King James Version
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.
Context
11 Let such a person consider this, that what we are in word by letters when we are absent, such are we also in deed when we are present.
12 For we are not bold to number or compare ourselves with some of those who commend themselves. But they themselves, measuring themselves by themselves, and comparing themselves with themselves, are without understanding.
13 But we will not boast beyond proper limits, but within the boundaries with which God appointed to us, which reach even to you.
