'Sent' in the Bible

And we have sent together with him the brother whose praise in the gospel is spread through all the churches;

and we have sent with them our brother, whom we have many times proved earnest in many things, but now much more earnest, by reason of the great confidence which he hath in you.

But I have sent the brethren, that our glorying on your behalf may not be made void in this respect; that, even as I said, ye may be prepared:

Did I take advantage of you by any one of them whom I have sent unto you?

I exhorted Titus, and I sent the brother with him. Did Titus take any advantage of you? walked we not in the same spirit? walked we not in the same steps?
