(34) He expounded.--The word may be noted as being the verb from which is formed the noun "interpretation" in 2Peter 1:20, and so takes its place in the coincidences of phraseology which connect that Epistle with this Gospel. (See Introduction.)

4:21-34 These declarations were intended to call the attention of the disciples to the word of Christ. By his thus instructing them, they were made able to instruct others; as candles are lighted, not to be covered, but to be placed on a candlestick, that they may give light to a room. This parable of the good seed, shows the manner in which the kingdom of God makes progress in the world. Let but the word of Christ have the place it ought to have in a soul, and it will show itself in a good conversation. It grows gradually: first the blade; then the ear; after that the full corn in the ear. When it is sprung up, it will go forward. The work of grace in the soul is, at first, but the day of small things; yet it has mighty products even now, while it is in its growth; but what will there be when it is perfected in heaven!But without a parable spake he not unto them,.... For the above reason, as well as for the accomplishment of Scripture; See Gill on Matthew 13:34, Matthew 13:35.

And when they were alone, he expounded all things to his disciples: after they returned with him from the sea side, to the house in Capernaum, where he usually was when there; see Matthew 13:36. The multitude being dismissed, he unfolded and explained all these parables to his disciples, and led them into a large knowledge of himself, and the mysteries of the kingdom of heaven; whereby they were furnished for the work he had called them to, and designed them for.
