2 Corinthians 10:11-13 New English Translation (NET Bible)
11 Let such a person consider this: What we say by letters when we are absent, we also are in actions when we are present.
12 For we would not dare to classify or compare ourselves with some of those who recommend themselves. But when they measure themselves by themselves and compare themselves with themselves, they are without understanding. 13 But we will not boast beyond certain limits, but will confine our boasting according to the limits of the work to which God has appointed us, that reaches even as far as you.
