(4) Yet the Lord hath not given you an heart to perceive.—“To mark the mercies of the Holy One, blessed be He! and to cleave unto Him” (Rashi). And so in Psalm 106:7, “Our fathers understood not Thy wonders in Egypt; they remembered not the multitude of Thy mercies.” (See also on Deuteronomy 31:16, &c.)

Deuteronomy 29:4. The Lord hath not given you a heart to perceive — Which he would have done had you sincerely and earnestly desired and asked it of him; and you are inexcusable that you have not, considering his signal mercies on the one hand, and awful judgments on the other, of which you have had such great experience, and which called loudly upon you to humble yourselves before him in true repentance, and seek his grace to enable you to understand and improve by such extraordinary dispensations and wonderful works. For he does not speak thus to excuse their wickedness, but to direct them to whom they must have recourse for a good understanding of God’s works; and to intimate that although the hearing ear, and the seeing eye, be the workmanship of God, yet their want of these was their own fault, and the just punishment of their former sins; their present case being like theirs in Isaiah’s time, who first shut their own eyes and ears that they might not see and hear, and would not understand, and then, by the righteous judgment of God, had their eyes and ears closed that they should not see, and hear, and understand. God’s readiness to do us good in other things, is a plain evidence, that if we have not grace, that best of gifts, it is our own fault and not his: he would have gathered us, and we would not.

29:1-9 Both former mercies, and fresh mercies, should be thought on by us as motives to obedience. The hearing ear, and seeing eye, and the understanding heart, are the gift of God. All that have them, have them from him. God gives not only food and raiment, but wealth and large possessions, to many to whom he does not give grace. Many enjoy the gifts, who have not hearts to perceive the Giver, nor the true design and use of the gifts. We are bound, in gratitude and interest, as well as in duty and faithfulness, to keep the words of the covenant.Ability to understand the things of God is the gift of God (compare 1 Corinthians 2:13-14); yet man is not guiltless if he lacks that ability. The people had it not because they had not felt their want of it, nor asked for it. Compare 2 Corinthians 3:14-15. 2. Moses called unto all Israel, … Ye have seen all that the Lord did, &c.—This appeal to the experience of the people, though made generally, was applicable only to that portion of them who had been very young at the period of the Exodus, and who remembered the marvellous transactions that preceded and followed that era. Yet, alas! those wonderful events made no good impression upon them (De 29:4). They were strangers to that grace of wisdom which is liberally given to all who ask it; and their insensibility was all the more inexcusable that so many miracles had been performed which might have led to a certain conviction of the presence and the power of God with them. The preservation of their clothes and shoes, the supply of daily food and fresh water—these continued without interruption or diminution during so many years' sojourn in the desert. They were miracles which unmistakably proclaimed the immediate hand of God and were performed for the express purpose of training them to a practical knowledge of, and habitual confidence in, Him. Their experience of this extraordinary goodness and care, together with their remembrance of the brilliant successes by which, with little exertion or loss on their part, God enabled them to acquire the valuable territory on which they stood, is mentioned again to enforce a faithful adherence to the covenant, as the direct and sure means of obtaining its promised blessings. This verse comes in by way of correction or exception to the foregoing clause in this manner, I said indeed, Ye have seen, &c., Deu 29:2, and thine eyes have seen, &c., but I must recall my words, for in truth you have not seen them; in seeing you have not seen, and perceiving you have not perceived them: you have perceived and seen them with the eyes of your body, but not with your minds and hearts; you have not seen them to any purpose; you have not yet learned rightly to understand the word and works of God, so as to know them for your good, and to make a right use of them, and to comply with them; which he expresseth thus,

the Lord hath not given you, & c., not to excuse their wickedness, but partly to direct them what course to take, and to whom they must have recourse for the amending of their former errors, and for a good understanding and improvement of God’s works; and partly to aggravate their sin, and to intimate that although the hearing ear, and the seeing eye, and the understanding heart, be the workmanship of God, Proverbs 20:12, and the effects of his special grace, Deu 30:6 Jeremiah 31:33 32:39, &c., yet their want of this grace was their own fault, and the just punishment of their former sins; their present case being like theirs in Isaiah’s time, who first shut their eyes and ears that they might not see and hear, and would not understand, and then by the tremendous, but righteous judgment of God, had their hearts made fat, and their eyes and ears closed, that they should not be able to see, and hear, and understand, as is manifest from the history of their carriage in the wilderness.

Yet the Lord hath not given you an heart to perceive,.... They had some of them seen the above miracles with their bodily eyes, but had not discerned with the eyes of their understanding the power of God displayed in them, the goodness of God to them on whose behalf they were wrought, in order to obtain their deliverance, and the vengeance of God on the Egyptians for detaining them; so Jarchi interprets it of an heart to know the mercies of the Lord, and to cleave unto him:

and eyes to see, and ears to hear, unto this day; to see and observe the gracious dealings of God with them, and to hearken to his voice and obey it: so the understanding heart, the seeing eye, and hearing ear, in things spiritual, are from the Lord, are special gifts of his grace, which he bestows on some, and not on others; see Proverbs 20:12. The Targum of Jonathan is,"the Word of the Lord did not give you an heart, &c.''

Yet the LORD hath not {d} given you an heart to perceive, and eyes to see, and ears to hear, unto this day.

(d) He shows that it is not in man's power to understand the mysteries of God if it is not given to him from above.
