Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.

For this cause I speak to them in parables, because seeing they do not see, and hearing they do not hear nor understand;

'Because of this, in similes do I speak to them, because seeing they do not see, and hearing they do not hear, nor understand,

I speak to them in figurative language for this reason, that while looking they do not see, and while hearing they neither hear nor understand.

For this reason I put things into the form of stories; because they see without seeing, and give ear without hearing, and the sense is not clear to them.

For this reason, I speak to them in parables: because seeing, they do not see, and hearing they do not hear, nor do they understand.

That is why I speak to them in parables, because, though they have eyes, they do not see, and though they have ears, they do not hear or understand.

For this reason I speak by parables. He says that he speaks to the multitude in an obscure manner, because they are not partakers of the true light. And yet, while he declares that a veil is spread over the blind, that they may remain in their darkness, he does not ascribe the blame of this to themselves, but takes occasion to commend more highly the grace bestowed on the Apostles, because it is not equally communicated to all. He assigns no cause for it, except the secret purpose of God; for which, as we shall afterwards see more fully, there is a good reason, though it has been concealed from us. It is not the only design of a parable to state, in an obscure manner, what God is not pleased to reveal clearly; but we have said that the parable now under our consideration was delivered by Christ, in order that the form of an allegory might present a doubtful riddle.

Because they seeing, see not - Mark Mark 4:12 and Luke Luke 8:10 say, "That seeing, they may not see etc.;" but there is no difference.
Matthew simply states the "fact," that though they saw the "natural" meaning of the story - though they literally understood the parable - yet they did not understand its "spiritual" signification. Mark and Luke do not state the "fact," but affirm that he spoke with this "intention" - implying that such "was" the result. Nor was there any dishonesty in this, or any unfair disguise. He had truths to state which he wished his "disciples particularly" to understand. They were of great importance to their ministry. Had he clearly and fully stated them to the Jews, they would have taken his life long before they did. He therefore chose to state the doctrines so that if their hearts had been right, and if they had not been malignant and blind, "they might have understood them." His doctrines he stated in the best possible way, and it was not his fault if they did not understand him. By little and little, in this way, he prepared many even of the Jews to receive the truth; by the only possible way of ever gaining access to their minds. It was, moreover, entirely proper and right to impart instruction to his disciples which he did not "intend" for others.

Therefore speak I to them in parables - On this account, viz. to lead them into a proper knowledge of God. I speak to them in parables, natural representations of spiritual truths, that they may be allured to inquire, and to find out the spirit, which is hidden under the letter; because, seeing the miracles which I have wrought, they see not, i.e. the end for which I have wrought them; and hearing my doctrines, they hear not, so as to profit by what is spoken; neither do they understand, ουδε συνιουσι, they do not lay their hearts to it. Is not this obviously our Lord's meaning? Who can suppose that he would employ his time in speaking enigmatically to them, on purpose that they might not understand what was spoken? Could the God of truth and sincerity act thus? If he had designed to act otherwise, he might have saved his time and labor, and not spoken at all, which would have answered the same end, viz. to leave them in gross ignorance.

Therefore speak I to them in parables,.... Because it was the will and pleasure of his Father to give the knowledge of divine mysteries to some, and not to others; and because even the outward good things they had, being wrongly used or abused by them, would be taken away from them:
and because they seeing, see not: they saw Christ with their bodily eyes, but not with an eye of faith; they saw the miracles he did, but did not discern, at least did not acknowledge the evidence of them, proving him to be the true Messiah.
And hearing, they hear not, neither do they understand: they heard externally, but not internally; they heard the sound of Christ's voice, but did not understand his words, even when he spake in the plainest and most intelligible manner; nor were they concerned to know the meaning of them: wherefore he spoke to them in this abstruse and parabolical way, that they might be what they really were, seers and not seers, hearers and not hearers, at least not understanding ones; and that what he said might remain sealed and hidden to them, as the things contained in the sealed book were to the Jews of old; the reason of which was, as a writer of their's (k) says, and which agrees with our Lord's reason and conduct here, , "because they were in parable and riddle".
(k) Abarbinel in Isaiah. 29. 11.

Therefore speak I to them in parables--which our Lord, be it observed, did not begin to do till His miracles were malignantly ascribed to Satan.
because they seeing, see not--They "saw," for the light shone on them as never light shone before; but they "saw not," for they closed their eyes.
and hearing, they hear not; neither do they understand--They "heard," for He taught them who "spake as never man spake"; but they "heard not," for they took nothing in, apprehending not the soul-penetrating, life-giving words addressed to them. In Mark and Luke (Mark 4:12; Luke 8:10), what is here expressed as a human fact is represented as the fulfilment of a divine purpose--"that seeing they may see, and not perceive," &c. The explanation of this lies in the statement of the foregoing verse--that, by a fixed law of the divine administration, the duty men voluntarily refuse to do, and in point of fact do not do, they at length become morally incapable of doing.

Because, seeing they see not. Do not see in the true light on account of their spiritual ignorance and depravity. The desire to see spiritually is essential to clear perceptions of truth.

Therefore I speak to them in parables, because seeing, they see not - In pursuance of this general rule, I do not give more knowledge to this people, be. cause they use not that which they have already: having all the means of seeing, hearing, and understanding, they use none of them: they do not effectually see, or hear, or understand any thing.
