וַיֹּ֨אמֶר יַעֲקֹ֜ב אֶל־שִׁמְע֣וֹן וְאֶל־לֵוִי֮ עֲכַרְתֶּ֣ם אֹתִי֒ לְהַבְאִישֵׁ֙נִי֙ בְּיֹשֵׁ֣ב הָאָ֔רֶץ בַּֽכְּנַעֲנִ֖י וּבַפְּרִזִּ֑י וַאֲנִי֙ מְתֵ֣י מִסְפָּ֔ר וְנֶאֶסְפ֤וּ עָלַי֙ וְהִכּ֔וּנִי וְנִשְׁמַדְתִּ֖י אֲנִ֥י וּבֵיתִֽי׃
At sinabi ni Jacob kina Simeon at Levi: “Ginulo ninyo ako, anupat ginawa ninyo akong kasuklam-suklam sa mga naninirahan sa lupain, sa mga Cananeo at sa mga Perezeo. Kaunti lamang ang aking mga tauhan; magtitipon sila laban sa akin at sasalakayin ako, at malilipol ako, ako at ang aking sambahayan.”
Gray Matter III
The Ramban derives support for his opinion from the fact that Yaakov strongly criticized Shimon and Levi’s actions (Bereishit 34:30). The Rambam could counter that the Torah (ibid. 31) records the retort of Shimon and Levi to this criticism, to which Yaakov does not respond. On the other hand, the Ramban could reply that Yaakov further criticized Shimon and Levi on his deathbed (Bereishit 49:5-7). Thus, the Torah gives the last word to Yaakov.
