1 Corinthians 16:18

For they refreshed my spirit and yours: acknowledge ye therefore them that are such. [These were the messengers which bore the Corinthian letter to Paul. Of them we know nothing more. What Paul says of them here was probably written to keep the Corinthians from showing resentment toward them for having told him the sad condition of the church. The thought seems to be that they refreshed the apostle by partially filling the void caused by the absence of the Corinthians, and they caused Paul to refresh the church at Corinth both by receiving personal messages from him, and causing him to write the letter. He asks that they be received as a refreshment from him, just as he had received them as such from them.]
