Matthew 13:13 - Clarke's commentary and critical notes on the Bible

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