Matthew Poole and continuators on 1 Corinthians 16:18

18 For they have refreshed my spirit and yours: therefore acknowledge ye them that are such .

It should seem that this Church had sent these three Persons to Paul at this time (as most think) at Ephesus, to acquaint him with the state of their Churches; these men supplied the want of that whole Churches coming, or they made a report to the Apostle of the Corinthians more fully, than they had done in their Letters. He adds, That they had refreshed his Spirit, not with bringing him any money, (for the Apostle hath told us, Chap. 9.15. that he gloried in this, That he had preached the Gospel to them freely, without being any charge to them) but by their visit, and the Conference that he had had with them about the state of that Church. The Apostle addeth, That they had refreshed their Spirits also; intimating, that their joy was his, and that what was a refreshing to him, ought also to be so to them: he therefore recommendeth these men, and such as they were, to be reverenced and respected by this Church.
