2 Corinthians 12:12-14

The signs of a true apostle were performed among you with all perseverance, by signs and wonders and miracles. For in what respect were you treated as inferior to the rest of the churches, except that I myself did not become a burden to you? Forgive me this wrong! Here for this third time I am ready to come to you, and I will not be a burden to you; for I do not seek what is yours, but you; for children are not responsible to save up for their parents, but parents for their children.
