(Genesis 27:35-36) "Is he not rightly named Jacob (Yaakov)?" This teaches that Esau cleared his throat and brought out the venom of his words. Three came with a trumped-up grievance: Cain, Esau, and Manasseh. Cain, as it is written (Genesis 4:13), "My iniquity is too great to bear." Esau, as it is written (below, verse 38), "Have you but one blessing, my father?" Manasseh: at first he called upon many gods, and in the end upon the God of his fathers.
Esau, Cain, and Manasseh and the Charge of a Trumped-Up Claim
Yalkut Shimoni on Torah 115:20
(בראשית כז לה-לו) הֲכִי קָרָא שְׁמוֹ יַעֲקֹב, מְלַמֵּד שֶׁחִכֵּךְ בִּגְרוֹנוֹ וְהוֹצִיא אֶת הַזְּמוֹרָה. שְׁלשָׁה בָּאוּ בָּעֲלִילָה, קַיִן, וְעֵשָׂו, וּמְנַשֶּׁה. קַיִן דִּכְתִיב (בראשית ד, יג) "גָּדוֹל עֲוֹנִי מִנְּשׂוֹא" עֵשָׂו דִּכְתִיב (להלן פסוק לח) הַבֲרָכָה אַחַת הִוא לְךָ אָבִי מְנַשֶּׁה בִּתְחִלָּה קָרָא לֶאֱלֹהוּת הַרְבֵּה, וּלְבַסּוֹף לֶאֱלֹהֵי אֲבוֹתָיו.
