Gill's Exposition of the Entire BibleAnd I have led you forty years in the wilderness,.... From the time of their coming out of Egypt unto that day, which though not quite complete, is given as a round number. Eupolemus (d), an Heathen writer, confirms this date of the ministry of Moses among the Israelites; he says, Moses performed the office of a prophet forty years: your clothes are not waxen old upon you: were not worn out; all those forty years they had been in the wilderness, they had never wanted clothes fitting for them, according to their age and stature, and which decayed not; See Gill on Deuteronomy 8:4, and thy shoe is not waxen old upon thy foot; which were necessary to wear in travelling, and especially in a rugged wilderness; and yet, thought they had been always in use during so long a time, were not worn out, which was really miraculous; See Gill on Deuteronomy 8:4. (d) Apud Euseb. Praepar. Evangel. l. 9. c. 30. p. 447.
Keil and Delitzsch Biblical Commentary on the Old TestamentWith the appeal to the gracious guidance of Israel by God through the desert, the address of Moses passes imperceptibly into an address from the Lord, just as in Deuteronomy 11:14. (On Deuteronomy 29:5, Deuteronomy 29:6, vid., Deuteronomy 8:3-4; on Deuteronomy 29:7, vid., Deuteronomy 2:26., and Deuteronomy 3:1. and Deuteronomy 3:12.).
Geneva Study BibleAnd I have led you forty years in the wilderness: your clothes are not waxen old upon you, and thy shoe is not waxen old upon thy foot.
Matthew Henry's Concise Commentary29:1-9 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. |
