5 not to engage in battle with them, for I will not give you even so much as a foot's length of their land, since I have given Mount Seir to Esau as a possession. 6 You shall purchase food from them for money, so that you may eat; and you shall also buy water from them for money, so that you may drink. 7 Surely the Lord your God has blessed you in all your undertakings; he knows your going through this great wilderness. These forty years the Lord your God has been with you; you have lacked nothing."
8 So we passed by our kin, the descendants of Esau who live in Seir, leaving behind the route of the Arabah, and leaving behind Elath and Ezion-geber. When we had headed out along the route of the wilderness of Moab, 9 the Lord said to me: "Do not harass Moab or engage them in battle, for I will not give you any of its land as a possession, since I have given Ar as a possession to the descendants of Lot."

Commentary on Deuteronomy 2:1-7
(Read Deuteronomy 2:1-7)
Only a short account of the long stay of Israel in the wilderness is given. God not only chastised them for their murmuring and unbelief, but prepared them for Canaan; by humbling them for sin, teaching them to mortify their lusts, to follow God, and to comfort themselves in him. Though Israel may be long kept waiting for deliverance and enlargement, it will come at last. Before God brought Israel to destroy their enemies in Canaan, he taught them to forgive their enemies in Edom. They must not, under pretence of God's covenant and conduct, think to seize all they could lay hands on. Dominion is not founded in grace. God's Israel shall be well placed, but must not expect to be placed alone in the midst of the earth. Religion must never be made a cloak for injustice. Scorn to be beholden to Edomites, when thou hast an all-sufficient God to depend upon. Use what thou hast, use it cheerfully. Thou hast experienced the care of the Divine providence, never use any crooked methods for thy supply. All this is equally to be applied to the experience of the believer.
Commentary on Deuteronomy 2:8-23
(Read Deuteronomy 2:8-23)
We have the origin of the Moabites, Edomites, and Ammonites. Moses also gives an instance older than any of these; the Caphtorims drove the Avims out of their country. These revolutions show what uncertain things wordly possessions are. It was so of old, and ever will be so. Families decline, and from them estates are transferred to families that increase; so little continuance is there in these things. This is recorded to encourage the children of Israel. If the providence of God has done this for Moabites and Ammonites, much more would his promise do it for Israel, his peculiar people. Cautions are given not to meddle with Moabites and Ammonites. Even wicked men must not be wronged. God gives and preserves outward blessings to wicked men; these are not the best things, he has better in store for his own children.
