2 Now Moses called all Israel and said to them: "You have seen all that the Lord 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 have seen, the signs, and those great wonders. 4 Yet the Lord has not given you a heart to perceive and eyes to see and ears to hear, to this very day. 5 And I have led you forty years in the wilderness. Your clothes have not worn out on you, and your sandals have not worn out on your feet. 6 You have not eaten bread, nor have you drunk wine or similar drink, that you may know 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.
