'Commend' in the Bible

Do we begin again to commend ourselves? or do we need, as some, commendatory letters to you, or commendatory from you?

For we do not again commend ourselves to you, but we are giving to you occasion of boast in our behalf, that ye may have such with those boasting in countenance, and not in heart.

For we dare not class ourselves or compare ourselves with some who commend themselves; but these, measuring themselves by themselves, and comparing themselves with themselves, are not intelligent.
