2 Moses called to all Israel, and said to them, You have seen all that Yahweh did before your eyes in the land of Egypt to Pharaoh, and to all his servants, and to all his land; 3 the great trials which your eyes saw, the signs, and those great wonders: 4 but Yahweh has not given you a heart to know, and eyes to see, and ears to hear, to this day. 5 I have led you forty years in the wilderness: your clothes have not grown old on you, and your shoes have not grown old on your feet. 6 You have not eaten bread, neither have you drunk wine or strong drink; that you may know that I am Yahweh your God.
Matthew Henry's Commentary on Deuteronomy 29:2-6
Commentary on Deuteronomy 29:1-9
(Read Deuteronomy 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.
