Matthew Poole and continuators on 2 Corinthians 8:20

20 Avoiding this, that no man should blame us in this abundance which is administred by us .

I have sent more than one as witnesses of what is done in this Service, that none might reflect upon those trusted with the Charity of divers Churches, as if they converted any part of it to their own private use, and did not distribute it to those for whom it was given. The Apostle here commendeth to all Ministers and Christians, a prudent foresight of such scandalous imputations, as they may be exposed to (be their sincerity what it will) from the men of the world, who have no good will towards them, and a provision against them. Paul could have trusted Titus in the distribution of these Alms, but he did not know what the World might say, had he discharged the trust alone; he therefore takes in one with him, to be a witness of his actions.
