'Sent' in the Bible

And judging by the stupendous grandeur of the revelations--therefore lest I should be over-elated there has been sent to me, like the agony of impalement, Satan's angel dealing blow after blow, lest I should be over-elated.

Have I gained any selfish advantage over you through any one of the messengers I have sent to you?

I begged Titus to visit you, and sent our other brother with him. Did Titus gain any selfish advantage over you? Were not he and I guided by one and the same Spirit, and did we not walk in the same steps?
