2 Corinthians 8:18-21

And with him we have sent a brother whose praise in the good news has gone through all the churches; And not only so, but he was marked out by the churches to go with us in the grace of this giving which we have undertaken to the glory of the Lord and to make clear that our mind was ready: And so that no man might be able to say anything against us in the business of this giving which has been put into our hands: For the business has been so ordered by us as to have the approval, not only of the Lord, but of men.
