Matthew 13:44

And hid (kai ekrupsen). Not necessarily bad morality. "He may have hid it to prevent it being stolen, or to prevent himself from being anticipated in buying a field" (Plummer). But if it was a piece of sharp practice, that is not the point of the parable. That is, the enormous wealth of the Kingdom for which any sacrifice, all that one has, is not too great a price to pay.
