John Chrysostom
Here again he disposes them to generosity. If, he says, so much is collected that I too must go, I will not refuse.
But he did not promise this directly and did not say, “When I come, I myself will carry it.” If he had said this at the very beginning, he would not have disposed them so much to increase the offering.
But afterward such an addition was good and timely. Therefore he neither promised it directly nor kept complete silence about it. First he said, “I will send,” and then he mentioned himself.
And in these words, “But if it is fitting that I go also,” he again leaves the matter to their will. That is, it depends on them to collect much, and enough that he too would not be ashamed to undertake the journey.
