2 And Moses said in the hearing of all Israel, You have seen all the Lord did before your eyes in the land of Egypt to Pharaoh and to all his servants and all his land; 3 The great tests which your eyes saw, and the signs and wonders: 4 But even to this day the Lord has not given you a mind open to knowledge, or seeing eyes or hearing ears. 5 For forty years I have been your guide through the waste land: your clothing has not become old on your backs, or your shoes on your feet. 6 You have had no bread, or wine, or strong drink: so that you might see that I am the Lord 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.
