Matthew 13:52

Every scribe - Minister of Christ: who is instructed - taught of God; in the kingdom of heaven - in the mysteries of the Gospel of Christ: out of his treasury - his granary or store-house; things new and old - a Jewish phrase for great plenty. A small degree of knowledge is not sufficient for a preacher of the Gospel. The sacred writings should be his treasure, and he should properly understand them. His knowledge does not consist in being furnished with a great variety of human learning, (though of this he should acquire as much as he can); but his knowledge consists in being well instructed in the things concerning the kingdom of heaven, and the art of conducting men thither. Again, it is not enough for a man to have these advantages in possession: he must bring them forth, and distribute them abroad. A good pastor will not, like a miser, keep these things to himself to please his fancy; nor, like a merchant, traffic with them, to enrich himself; but, like a bountiful father or householder, distribute them with a liberal through judicious hand, for the comfort and support of the whole heavenly family.

A preacher whose mind is well stored with Divine truths, and who has a sound judgment, will suit his discourses to the circumstances and states of his hearers. He who preaches the same sermon to every congregation, gives the fullest proof that, however well he may speak, he is not a scribe who is instructed in the kingdom of heaven. Some have thought that old and new things here, which imply the produce of the past and the produce of the present year, may also refer to the old and new covenants - a proper knowledge of the Old Testament Scriptures, and of the doctrines of Christ as contained in the New. No man can properly understand the Old Testament but through the medium of the New, nor can the New be so forcibly or successfully applied to the conscience of a sinner as through the medium of the Old. The law is still a schoolmaster to lead men to Christ - by it is the knowledge of sin, and, without it, there can be no conviction - where it ends, the Gospel begins, as by the Gospel alone is salvation from sin. See the whole of the comment on the Pentateuch.

13:52 Every scribe instructed unto the kingdom of heaven - That is, every duly prepared preacher of the Gospel has a treasure of Divine knowledge, out of which he is able to bring forth all sorts of instructions. The word treasure signifies any collection of things whatsoever, and the places where such collections are kept.
