'Sent' in the Bible

And we have sent with him the brother, whose praise is in the gospel throughout all the churches;

And we have sent with them our brother, whom we have oftentimes proved diligent in many things, but now much more diligent, upon the great confidence which I have in you.

Yet have I sent the brethren, lest our boasting of you should be in vain in this behalf; that, as I said, ye may be ready:

Did I make a gain of you by any of them whom I sent unto you?

I desired Titus, and with him I sent a brother. Did Titus make a gain of you? walked we not in the same spirit? walked we not in the same steps?
