With regard to Geviha ben Pesisa and his cleverness in debate, the Talmud cites several incidents where he represented the Jewish people in debates. The Sages taught in Megillat Ta'anit: On the twenty-fourth day in Nisan it is a joyous day, since the usurpers [dimusana'ei] were expelled from Judea and Jerusalem. When the people of Afrikiya came to judgment with the Jewish people before the emperor, Alexander of Macedon, they said to him: The land of Canaan is ours, as it is written: “This is the land that shall fall to you as an inheritance, the land of Canaan according to its borders” (Numbers 34:2). And the people of Afrikiya said, referring to themselves: Canaan is the forefather of these people.
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 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 the land of Canaan is yours? 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 he said: Cursed will be Canaan; a slave of slaves shall he be to his brethren” (Genesis 9:25). And with regard to a slave who acquired property, the slave belongs to whom and the property belongs to whom? The slave and his property belong to the master. And moreover, it is several years now that you have not served us. Therefore, not only are you not entitled to the land, there are additional debts that must be repaid, as well as a return to enslavement.
Alexander the king said to the people of Afrikiya: Provide Geviha ben Pesisa with a response to his claims. They said to Alexander: Give us time; give us three days to consider the matter. The emperor gave them the requested time and they examined the matter and did not find a response to the claims. Immediately, they fled and abandoned their fields when they were sown and their vineyards when they were planted. The Gemara adds: And since that year was a Sabbatical Year, with the accompanying restrictions on agricultural activity, this benefited the Jewish people, as they were able to consume the produce of those fields and vineyards.
The Talmud relates: And on another occasion, the descendants of Ishmael and the descendants of Keturah came to judgment with the Jewish people before Alexander of Macedon. They said to the Jewish people before Alexander: The land of Canaan is both ours and yours, as it is written: “And these are the generations of Ishmael, son of Abraham, whom Hagar the Egyptian, Sarah's maidservant, bore unto Abraham” (Genesis 25:12), and it is written: “And these are the generations of Isaac, son of Abraham” (Genesis 25:19). Therefore, the land should be divided between Abraham's heirs.
Geviha ben Pesisa said to the descendants of Ishmael: From where are you citing proof that the land of Canaan belongs to both you and the Jewish people? 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 Abraham gave all that he had to Isaac. But to the sons of the concubines that Abraham had, Abraham gave gifts, and he sent them away from his son, while he yet lived, eastward, to the east country” (Genesis 25:5–6). In the case of a father who gave a document of bequest [agatin] to his sons during his lifetime and sent one of the sons away from the other, does the one who was sent away have any claim against the other? The father himself divided his property.
