Deuteronomy 29:5

“And I have led you forty years in the wilderness, etc.] From the time of their coming out of Egypt unto that day, which though not quite complete, is given as a round number. Eupolemus f541, 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 “<050804>Deuteronomy 8:4”); and thy shoe is not waxen old upon thy foot; which were necessary to wear in travelling, and…”

“I have led: Deu 1:3, Deu 8:2 your clothes: Deu 8:4; Neh 9:21; Mat 6:31, Mat 6:32 and thy shoe: Jos 9:5, Jos 9:13; Mat 10:10 Deuteronomy 29:6”

“With 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 Deu 11:14. (On Deu 29:5, Deu 29:6, vid., Deu 8:3-4; on Deu 29:7, vid., Deu 2:26., and Deu 3:1. and Deu 3:12.). Deuteronomy 29:9”
