let no man consult only his private interest, but let every man consult likewise the interest of others.

for there is no one that is so dear to me as he, and no one will more sincerely interest himself in your concerns.

I rejoiced greatly in the Lord, that now at last you have renewed your concern for me; indeed, you were concerned about me before, but you had no opportunity to show it.

It is not the money I am anxious for; what I am anxious for is the interest that accumulates in this way to your divine credit!
