Parshat Vayigash

 There is a famous discussion in the Talmud Bavli, Tractate Sanhedrin 91 which discusses how the Egyptians claimed to Alexander the Great, that we owe them the utensils that we borrowed when we went out of Egypt. The Gemara relates a response that Geviha ben Pesisa answered to Alexander the Great(see the gemara that I pasted below). 

 I wonder why the Gemara didn't bring a response from this weeks Parsha Vayigash, Where Pharoah tells Joseph (in perek 45 pasukim 18-20), 

 וּקְח֧וּ אֶת־אֲבִיכֶ֛ם וְאֶת־בָּתֵּיכֶ֖ם וּבֹ֣אוּ אֵלָ֑י וְאֶתְּנָ֣ה לָכֶ֗ם אֶת־טוּב֙ אֶ֣רֶץ מִצְרַ֔יִם וְאִכְל֖וּ אֶת־חֵ֥לֶב הָאָֽרֶץ׃ וְאַתָּ֥ה צֻוֵּ֖יתָה זֹ֣את עֲשׂ֑וּ קְחוּ־לָכֶם֩ מֵאֶ֨רֶץ מִצְרַ֜יִם עֲגָל֗וֹת לְטַפְּכֶם֙ וְלִנְשֵׁיכֶ֔ם וּנְשָׂאתֶ֥ם אֶת־אֲבִיכֶ֖ם וּבָאתֶֽם׃ וְעֵ֣ינְכֶ֔ם אַל־תָּחֹ֖ס עַל־כְּלֵיכֶ֑ם כִּי־ט֛וּב כָּל־אֶ֥רֶץ מִצְרַ֖יִם לָכֶ֥ם הֽוּא׃ 

 Take your father and your households and come to me; I will give you the best of the land of Egypt and you shall live off the fat of the land.’ And you are bidden [to add], ‘Do as follows: take from the land of Egypt wagons for your children and your wives, and bring your father here. And never mind your belongings, for the best of all the land of Egypt shall be yours.’” So we see from the above pasukim, that Pharoah offered Joseph and his family what they rightfully took with them, when they left Egypt... 

 Talmud Sanhedrin 91a 

 שוב פעם אחת באו בני מצרים לדון עם ישראל לפני אלכסנדרוס מוקדון אמרו לו הרי הוא אומר (שמות יב, לו) וה' נתן את חן העם בעיני מצרים וישאילום תנו לנו כסף וזהב שנטלתם ממנו אמר גביהא בן פסיסא לחכמים תנו לי רשות ואלך ואדון עמהן לפני אלכסנדרוס אם ינצחוני אמרו להם הדיוט שבנו נצחתם ואם אני אנצח אותם אמרו להם תורת משה רבינו נצחתכם נתנו לו רשות והלך ודן עמהן אמר להן מהיכן אתם מביאין ראייה אמרו לו מן התורה אמר להן אף אני לא אביא לכם ראייה אלא מן התורה שנאמר (שמות יב, מ) ומושב בני ישראל אשר ישבו במצרים שלשים שנה וארבע מאות שנה תנו לנו שכר עבודה של ששים ריבוא ששיעבדתם במצרים שלשים שנה וארבע מאות שנה 

 The Gemara relates: On another occasion, the people of Egypt came to judgment with the Jewish people before Alexander of Macedon. The Egyptian people said to Alexander: It says in the Torah: “And the Lord gave the people favor in the eyes of Egypt, and they lent them” (Exodus 12:36). Give us the silver and gold that you took from us; you claimed that you were borrowing it and you never returned it. Geviha ben Pesisa said to the Sages: Give me permission and I will go and deliberate with them before Alexander of Macedon. If they will defeat me, say to them: You have defeated an ordinary person from among us, and until you overcome our Sages, it is no victory. And if I will defeat them, say to them: The Torah of Moses, our teacher, defeated you, and attribute no significance to me. The Sages gave him permission, and he went and deliberated with them. Geviha ben Pesisa said to them: From where are you citing proof that you are entitled to the silver and gold? They said to him: From the Torah. Geviha ben Pesisa said to them: I too will cite proof to you only from the Torah, as it is stated: “And the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years” (Exodus 12:40), during which they were enslaved to Egypt, engaged in hard manual labor. Give us the wages for the work performed by the 600,000 men above the age of twenty (see Exodus 12:37) whom you enslaved in Egypt for four hundred and thirty years.
