5-7. Meddle not with them--that is, "which dwell in Seir" (De 2:4) --for there was another branch of Esau's posterity, namely, the Amalekites, who were to be fought against and destroyed (Ge 36:12; Ex 17:14; De 25:17). But the people of Edom were not to be injured, either in their persons or property. And although the approach of so vast a nomadic horde as the Israelites naturally created apprehension, they were to take no advantage of the prevailing terror to compel the Edomites to accept whatever terms they imposed. They were merely to pass "through" or along their border, and to buy meat and water of them for money (De 2:6). The people, kinder than their king, did sell them bread, meat, fruits, and water in their passage along their border (De 2:29), in the same manner as the Syrian caravan of Mecca is now supplied by the people of the same mountains, who meet the pilgrims as at a fair or market on the hadji route [ROBINSON]. Although the Israelites still enjoyed a daily supply of the manna, there was no prohibition against their eating other food when opportunity afforded. Only they were not to cherish an inordinate desire for it. Water is a scarce commodity and is often paid for by travellers in those parts. It was the more incumbent on the Israelites to do so, as, by the blessing of God, they possessed plenty of means to purchase, and the long-continued experience of the extraordinary goodness of God to them, should inspire such confidence in Him as would suppress the smallest thought of resorting to fraud or violence in supplying their wants.
