This and the two parables following are recorded by Matthew only; and the place assigned them in his narrative indicates that they were spoken to the disciples alone, in the house, after the multitude had departed. The quest for treasure-trove is always fascinating. Instances of finding buried valuables were not uncommon in the time of which we speak, since the practise of so concealing treasure was usual with people exposed to bandit incursions and hostile invasion. Observe that the fortunate and happy man is represented as finding the treasure seemingly by accident rather than as a result of diligent search. He gladly sold all that he possessed to make possible his purchase of the field. The hidden treasure is the kingdom of heaven; when a man finds that, he ought to be ready to sacrifice all that he has, if by so doing he may gain possession. His joy in the new acquisition will be unbounded; and, if he but remain a worthy holder, the riches thereof shall be his beyond the grave.[636] Casuists have raised the question of propriety as to the man's course of action in the story, inasmuch as he concealed the fact of his discovery from the owner of the field, to whom the treasure, they say, rightly belonged. Whatever opinion one may hold as to the ethics of the man's procedure, his act was not illegal, since there was an express provision in Jewish law that the purchaser of land became the legal owner of everything the ground contained.[637] Assuredly Jesus commended no dishonest course; and had not the story been in every detail probable, its effect as a parable would have been lost. The Master taught by this illustration that when once the treasure of the kingdom is found, the finder should lose no time nor shrink from any sacrifice needful to insure his title thereto. THE PEARL OF GREAT PRICE. "Again, the kingdom of heaven is like unto a merchant man, seeking goodly pearls: who, when he had found one pearl of great price, went and sold all that he had, and bought it."[638]
