The parable of the hidden treasure found. Matthew only. It seems probable, from verse 51, that this and the next two parables were spoken to the disciples in private. They alone would appreciate the value of what they had found; to them alone could the warning be as yet given, that it is not sufficient to have been gathered within the gospel net. Observe in this parable that the treasure was found by chance, and it was near to the man without his knowing it. Again. To be omitted, with the Revised Version and Westcott and Hort. Its absence (contrast verses 45, 47) suggests that this parable is the first of a group, marked as such either by our Lord beginning with it after he had made a pause, or by merely coming first in one of the sources that the evangelist used. The kingdom of heaven (verse 24, note) is like unto treasure hid in a field (cf. Proverbs 2:4). Hid (hidden, Revised Version, κεκρυμμένῳ). It was not there by accident; it had been purposely placed there, hid by its former possessor for safety (Matthew 25:18, Matthew 25:25). Observe that, doubtless unintentionally on the part of the evangelist, the parable forms in this respect the complement to verse 35b. In a field ( ἐν τῷ ἀγρῷ); in the field (Revised Version); cf. Matthew 1:23, note. The which when a man hath found, he hideth; which a man found, and hid (Revised Version). For fear some one else should take it. Premature assertion would lose the man the treasure. (For a similar truth in spiritual things, cf. Galatians 1:17.) And for joy thereof. So also the margin of the Revised Version; but and in his joy (Revised Version) is better ( καὶ ἀπὸ τῆς χαρᾶς αὐτοῦ). Goeth and selleth all that he hath, and buyeth that field. Goeth … selleth … buyeth. All in the present tense. Our Lord in this parable (contrast verse 46) brings the man vividly before us in each separate stage of his action. For the self-denial that is a necessary of acquiring gospel privileges, comp. Matthew 19:21 (where contrast the young man's grief with the joy spoken of here). Field. Observe that, though the figure is the same as in Matthew 19:24, the thing signified is very different. Here field represents merely that which contains the treasure, perhaps the outward profession of Christianity. All. Westcott and Hort omit, chiefly on the authority of the Vatican manuscript (cf. verse 46, note). And buyeth that field. Into the morality of the action our Lord does not enter; he only illustrates his teaching by an incident that must have happened not un-frequently in a country like Palestine, which had already been the scene of so many wars. But the transaction "was, at least, in entire accordance with Jewish law. If a man had found a treasure in loose coins among the corn, it would certainly be his, if he bought the corn. If he had found it on the ground, or in the soil, it would equally certainly belong to him, if he could claim ownership of the soil, and even if the field were not his own, unless others could prove their right to it. The law went so far as to adjudge to the purchaser of fruits anything found among these fruits" (Edersheim, 'Life,' 1.595).
The parable of the pearl merchant, Matthew only. Observe in this parable that the merchant is accustomed to deal in pearls, and is searching for good ones, when he meets with one worth more than the others he possesses all put together. If the former parable described one who finds the gospel as it were by chance (e.g. the woman of Samaria), this speaks of one who has long been searching for truth (e.g. Andrew and John, the Ethiopian eunuch).
