In the second chapter, Moshe continues his review of the nation’s travels. This chapter serves a double purpose. The first is to recount the travels, but the second is to provide background for how the people should act towards the nations that surround the land. The seven nations in the land are supposed to be wiped out. But what about those around the land? Here, God has a different plan.
Three of the nations are given special protection—Ammon, Moav, and the sons of Esav. Esav is protected based on the blessing that Yitzchak granted Esav after Yaacov was given the firstborn blessing:
“And Isaac answered and said to Esau… By your sword shall you live… but when you gain the upper hand, you shall throw his yoke from off your neck.” (Genesis 27:39–40)
וַיַּעַן יִצְחָק אָבִיו וַיֹּאמֶר אֵלָיו הִנֵּה מִשְׁמַנֵּי הָאָרֶץ יִהְיֶה מוֹשָׁבֶךָ… וְעַל־חַרְבְּךָ תִחְיֶה וְאֶת־אָחִיךָ תַּעֲבֹד וְהָיָה כַּאֲשֶׁר תָּרִיד וּפָרַקְתָּ עֻלּוֹ מֵעַל צַוָּארֶךָ
Ammon and Moav are the descendants of Lot and his daughters. God protects their land because of Lot’s connection to Avraham:
“Do not harass Moab or provoke them to war, for I will not give you any of their land as a possession, for I have given Ar to the descendants of Lot as a possession.” (Deuteronomy 2:9)
אַל־תָּצַר אֶת־מוֹאָב וְאַל־תִּתְגָּר בָּם מִלְחָמָה כִּי לֹא־אֶתֵּן לְךָ מֵאַרְצוֹ יְרֻשָּׁה כִּי לִבְנֵי־לוֹט נָתַתִּי אֶת־עָר יְרֻשָּׁה
Similarly, regarding Ammon:
“When you approach the territory of the Ammonites, do not harass them or provoke them; for I will not give you any of the land of the Ammonites as a possession, because I have given it as a possession to the descendants of Lot.” (Deuteronomy 2:19)
וְקָרַבְתָּ מוּל בְּנֵי עַמּוֹן אַל־תְּצֻרֵם וְאַל־תִּתְגָּר בָּם כִּי לֹא־אֶתֵּן מֵאֶרֶץ בְּנֵי־עַמּוֹן לְךָ יְרֻשָּׁה כִּי לִבְנֵי־לוֹט נְתַתִּיהָ יְרֻשָּׁה
All the other nations surrounding the land are fair game. God even pulls the old “harden his heart” trick from Pharaoh in Egypt to provoke a war between the Israelites and Sihon:
“But King Sihon of Heshbon refused to let us pass through, for the Lord your God hardened his spirit and stiffened his heart in order to deliver him into your power.” (Deuteronomy 2:30)
וְלֹא־אָבָה סִיחוֹן מֶלֶךְ־חֶשְׁבּוֹן הַעֲבִירֵנוּ בּוֹ כִּי־הִקְשָׁה ה׳ אֱלֹהֶיךָ אֶת־רוּחוֹ וְאִמֵּץ אֶת־לְבָבוֹ לְמַעַן תִּתּוֹ בְיָדְךָ כַּיּוֹם הַזֶּה
Two interesting things about the familiar descendants. The first is that the promise to not provoke Moav at first seems out of place given what happened with Balaam and Balak, king of Moav. Moav’s Lot connction may explain why God demands revenge against Midian only, and not Moav:
“‘Avenge the Israelite people on the Midianites; then you shall be gathered to your kin.’” (Numbers 31:2)
Even though Moav was involved in the initial planning:
“Moab was alarmed because the people were so numerous… and Moab said to the elders of Midian, ‘Now this horde will lick clean all that is about us…’” (Numbers 22:3–4)
The second point is that the Israelites will not always remain peaceful with the descendants of Esav. The proclamation in this chapter by God that He will grant the sons of Esav the land of Seir also has a hidden warning:
“Do not provoke them, for I will not give you any of their land, not even enough to set foot on, for I have given Mount Seir to Esau as a possession.” (Deuteronomy 2:5)
Recall that Yitzchak’s blessing was that when one rises, the other will fall. At this point Israel is on the rise. They are powerful and have the ability to subdue the sons of Esav—but God says no. Instead, the sons of Esav will live on the borderlands as a constant reminder that if Israel begins to fall, that same blessing will come true and the sons of Esav will take over. Overall, however, the perek reads as a recap looking backward to strengthen the people's resolve to go forward-- you have encountered enemies and beat them in military battles. There are always issues but you will prevail.
