2 Corinthians 12:12-14

The signs that indicate a genuine apostle were performed among you fully and most patiently—signs and wonders and miracles. For in what respect were you treated as inferior to the rest of the churches, except [for the fact] that I did not burden you [with my financial support]? Forgive me [for doing you] this injustice! Now for the third time I am ready to visit you. I will not burden you [financially], because I do not want what is yours [not your money or your possessions], but you. For children are not responsible to save up for their parents, but parents for their children.
