Another interpretation: "And he commanded them, saying" (Genesis 32:5) means: Do not say that when he left his father's house he took nothing from the family estate, but rather, "By my own wages I acquired all these camps by my own strength," as it is said, "and now I have become two camps" (Genesis 32:11). In the hour when Jacob our father called Esau "my lord," the Holy One, blessed be He, said to him: You have lowered yourself before your brother and called him "lord" eight times; I will raise up from him eight kings before your sons, as it is written, "And these are the kings who reigned in the land of Edom before any king reigned over the children of Israel" (Genesis 36:31). Esau said to him: If you come in peace, I am prepared to meet you; and if you come for war, I am against you. I have mighty men and warriors, and I speak a word before the Holy One, blessed be He, and He does it, as it is said, "He fulfills the desire of those who fear Him" (Psalms 145:19).
Because Jacob Called Esau My Lord Eight Kings of Edom Arose First
Yalkut Shimoni on Torah 130:19
דָּבָר אַחֵר, וַיְצַו אֹתָם לֵאמֹר אַל תֹּאמַר, כְּשֶׁיָּצָא נָטַל כְּלוּם מִתְּפֻסַּת בֵּית אָבִיו אֶלָּא בְּשָׂכָר קָנִיתִי כָּל הַמַּחֲנוֹת הָאֵלּוּ בְּכֹחִי, שֶׁנֶּאֱמַר "וְעַתָּה הָיִיתִי לִשְׁנֵי מַחֲנוֹת". בְּאוֹתָהּ שָׁעָה שֶׁקָּרָא יַעֲקֹב אָבִינוּ לְעֵשָׂו אֲדוֹנִי, אָמַר לוֹ הַקָּדוֹשׁ בָּרוּךְ הוּא, אַתָּה הִשְׁפַּלְתָּ אֶת עַצְמְךָ לִפְנֵי אָחִיךָ וְקָרָאתָ אוֹתוֹ אָדוֹן שְׁמֹנֶה פְּעָמִים אֲנִי מַעֲמִיד מִמֶּנּוּ שְׁמֹנָה מְלָכִים קֹדֶם לְבָנֶיךָ, דִּכְתִיב "וְאֵלֶּה הַמְּלָכִים אֲשֶׁר מָלְכוּ בְּאֶרֶץ אֱדוֹם לִפְנֵי מְלָךְ מֶלֶךְ לִבְנֵי יִשְׂרָאֵל". אָמַר לֵיהּ, אִם לְשָׁלוֹם אַתָּה, מְתֻקָּן אֲנִי כְּנֶגְדְּךָ, וְאִם לְמִלְחָמָה אֲנִי כְּנֶגְדְּךָ, יֵשׁ לִי גִּבּוֹרִים וּבַעֲלֵי מִלְחָמָה, וְאוֹמַר לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא דָּבָר וְהוּא עוֹשֶׂה, שֶׁנֶּאֱמַר (תהלים קמה, יט) "רְצוֹן יְרֵאָיו יַעֲשֶׂה".
