וַיֹּאמֶר אֵלָיו אֱדוֹם לֹא תַּעֲבֹר בִּי. זֶה שֶׁאָמַר הַכָּתוּב: אֲנִי שָׁלוֹם וְכִי אֲדַבֵּר הֵמָּה לַמִּלְחָמָה (תהלים קכ, ז). וּמִנַּיִן שֶׁכֵּן אָמַר לָהֶם הַקָּדוֹשׁ בָּרוּךְ הוּא שֶׁאֵין מַנִּיחִין אוֹתָן לַעֲבֹר וְלֹא הַכֹּל מֵהֶן, שֶׁאֲנִי הוּא שֶׁרוֹצֶה, שֶׁנֶּאֱמַר: אַל תִּתְגָּרוּ בָם כִּי לֹא אֶתֵּן לָכֶם וְגוֹ' (דברים ב, ה). וּכְתִיב: וַיְמָאֵן אֱדֹם נָתֹן אֶת יִשְׂרָאֵל וְאַחַר כֵן שָׁלְחוּ אֶל מֶלֶךְ מוֹאָב וְלֹא אָבָה. אַף עַל פִּי שֶׁאֵינוֹ מְפֹרָשׁ כָּאן, הֲרֵי מְפֹרָשׁ בְּשׁוֹפְטִים. מְלַמֵּד, שֶׁהַכֹּל בְּרוּחַ הַקֹּדֶשׁ. שֶׁלֹּא הָיָה בְּכֻלָּן קַל מִן יִפְתַּח, וְהוּא פֵּרֵשׁ, שֶׁנֶּאֱמַר: וַיִּשְׁלַח יִשְׂרָאֵל מַלְאָכִים אֶל מֶלֶךְ אֱדֹם לֵאמֹר, אֶעֶבְּרָה נָא בְּאַרְצְךָ (שופטים יא, יז). וְאַף מֹשֶׁה רָמַז, שֶׁנֶּאֱמַר: כַּאֲשֶׁר עָשׂוּ לִי בְּנֵי עֵשָׂו הַיּוֹשְׁבִים בְּשֵׂעִיר וְגוֹ' (דברים ב, כט).

(Numb. 20:18:) “But Edom said unto him, “You shall not pass through me.’” This text is related to Ps. 120:7), “I am for peace; but when I speak, they are for war.” Where is it shown that the Holy One, blessed be He, also told them that they would not permit you to pass, [that] everything is not due to them, but [that] it is I who wills it? Where it is stated (in Deut. 2:5), “Do not engage them in battle, for I will not give you [enough of their land for (even) the sole of a foot to tread on].” And it is written (in Numb 20:21), “So Edom would not let [Israel cross their territory].” And afterwards, they sent [a request] to the king of Moab, and he would not let [Israel cross his territory either]. And even though it is not explained here, behold it is explained in Judges. [This] teaches that it was all [said] with the holy spirit. As there was no one lighter in all [the speakers] then Jephthah, and [yet] he explained [it]. It is so stated (in Jud. 11:17), “Israel then sent messengers to the king of Edom, saying, ‘Allow us to cross your country’; [but the king of Edom would not consent; they also sent a mission to the king of Moab, and he refused].” And Moses also indicated [this], as stated (in Deut. 2:29), “As the descendants of Esau who dwell in Seir did for me, [and the Moabites who dwell in Ar].”
