A.T. Robertson Commentary Matthew 13:44

"The kingdom of heaven is like unto a treasure hidden in the field; which a man found, and hid; and in his joy he goeth and selleth all that he hath, and buyeth that field." — Matthew 13:44 (ASV)

And hid (κα εκρυψεν). 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.
