"Until I come to my lord to Seir" — Rabbi Abbahu said: We went over the whole of Scripture and we did not find that Jacob ever went to Esau at Mount Seir in his days. Is it possible that Jacob, who was a man of truth, would deceive him? Rather, when does he come to him? In the time to come, as it is written, "And saviors shall come up on Mount Zion to judge the mountain of Esau" (Obadiah 1:21).
Jacob Never Went to Seir Until the End of Days
Yalkut Shimoni on Torah 133:23
עַד אֲשֶׁר אָבֹא אֶל אֲדֹנִי שֵׂעִירָה, אָמַר רַבִּי אַבָּהוּ, חָזַרְנוּ עַל כָּל הַמִּקְרָא וְלֹא מָצִינוּ שֶׁהָלַךְ יַעֲקֹב אֵצֶל עֵשָׂו לְהַר שֵׂעִיר מִיָמָיו, אֶפְשַׁר יַעֲקֹב אֲמִתִּי הָיָה מְרַמֶּה בֵּיהּ אֶלָא אֵימָתַי הוּא בָּא אֶצְלוֹ, לֶעָתִיד לָבֹא, הֲדָא הוּא דִּכְתִיב "וְעָלוּ מוֹשִׁיעִים בְּהַר צִיּוֹן לִשְׁפֹּט אֶת הַר עֵשָׂו".
