What does Jiya say that shows his humility when the Old Gentleman says that Jiya is the best boy in the village?

Jiya asks why the Old Gentleman did not ask the other orphans from the village to be his sons and daughters, and when the Old Gentleman says he heard Jiya was the best boy in the village, Jiya objects that he is no better than the others, so the Old Gentleman says he will do without a son.
