'Commend' in the Bible

I commend to you Phoebe, our sister, who is a servant of the assembly that is at Cenchreae,

But food will not commend us to God. For neither, if we don't eat, are we the worse; nor, if we eat, are we the better.

Are we beginning again to commend ourselves? Or do we need, as do some, letters of commendation to you or from you?

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.
