5. Mose 8:9

Moses had charged parents in teaching their children to whet the word of God upon them (Deu 6:7) by frequent repetition of the same things over and over again; and here he himself takes the same method of instructing the Israelites as his children, frequently inculcating the same precepts and cautions, with the same motives or arguments to enforce them, that what they heard so often might abide with them. In this chapter Moses gives them, I. General exhortations to obedience (Deu 8:1, Deu 8:6). II. A review of the great things God had done for them in the wilderness, as a good argument for obedience (Deu 8:2-5, Deu 8:15, Deu 8:16). III. A prospect of the good land into which God would now bring them (Deu 8:7-9). IV. A necessary caution against the temptations of a prosperous condition (Deu 8:10-14, and Deu 8:17, Deu 8:18). V. A fair warning of the fatal consequences of apostasy from God (Deu 8:19, Deu 8:20).

8:9 Iron was not widely used in this period of the Bronze Age because the process of smelting and working it was known to only a few cultures (see 1 Sam 13:19-21). The time would come when Israel would exploit this vastly superior metal (see Josh 17:16-18; 1 Kgs 6:7; 2 Kgs 6:5; 1 Chr 22:3).
