Talmud - Kiddushin 11b קידושין י״א ב׳

But with regard to a claim that someone has not returned a deposit or loan, when the defendant admits that only part of the claim is true, it is written: “If a man deliver to his neighbor money or vessels to guard and it be stolen out of the man’s house” (Exodus 22:6). The following verses teach that if the thief is not found, the case is brought to a court, where the defendant must take an oath. And we learned in a mishna with regard to one who admits to part of a claim (Shevuot 38b): The oath administered by the judges to one who admits to part of a claim is administered only when the claim is for at least two silver ma’a, and the defendant’s admission is to at least the value of one peruta. If every sum of money mentioned in the Torah is referring to Tyrian coinage, how did the Sages arrive at the amount of two ma’a in this case?

The Gemara explains: There, the halakha is derived from a juxtaposition, as the “money” mentioned in the verse is similar to “vessels”: Just as the word “vessels” indicates at least two, so too “money” is referring to at least two coins. And just as money is a significant item, so too the vessels must be a significant item.

The Gemara asks: But there is the case of the redemption of second tithe, as it is written: “And bind up the money in your hand” (Deuteronomy 14:25). And yet we learned in a mishna (Ma’aser Sheni 2:8): With regard to one who exchanges copper coins of second-tithe money for a sela, Beit Shammai say: He may exchange the copper coins for the entire silver sela. This mishna indicates that second-tithe money, mentioned in the Torah, can be in the form of copper coins, and it is not required to be in the form of silver coins. The Gemara explains that the verse does not say money, but “the money.” The addition of the article serves as an amplification. In other words, this addition teaches that second-tithe money can be in any coinage, including copper coins.

The Gemara asks: But there is the case of consecrated property, as it is written: “And he will give the money and it will be assured to him” (see Leviticus 27:19). And Shmuel says: With regard to consecrated property worth one hundred dinars, which was redeemed for an item worth one peruta, it is redeemed. Although the word “money” is stated in the Torah, a copper peruta may be used. The Gemara answers: There too, there is a reason for this unusual halakha, as he derives this ruling from a verbal analogy of the terms “money” mentioned here and “money” from tithes. Consequently, one may use any type of coin in this case as well.

The Gemara asks: But there is the case of the betrothal of a woman, as it is written: “When a man takes a woman and engages in sexual intercourse with her” (Deuteronomy 24:1), and one derives betrothal through money by a verbal analogy of the term “taking” used here and “taking” from the case of the field of Ephron. And yet we learned in the mishna that Beit Hillel say one can betroth a woman with one peruta or with any item that is worth one peruta. If so, shall we say that Rav Asi, who claims that all sums of money mentioned in the Torah are in Tyrian coinage, stated his opinion in accordance with the opinion of Beit Shammai?

Rather, the Gemara suggests an alternative explanation: If this was stated, it was stated like this: Rav Yehuda says that Rav Asi says: Every set amount of money stated in the Torah, i.e., when a specific amount is mentioned, is referring to Tyrian coinage, and any amount of money set by rabbinic law is in provincial coinage.

The Gemara asks: If so, what is Rav Asi teaching us? We have already learned all of these halakhot explicitly (Bekhorot 49b): The payment of five sela for the redemption of a firstborn son (Numbers 18:16); the payment of thirty sela for a slave, paid by the owner of the ox that killed the slave (Exodus 21:32); the fifty sela paid by a rapist and by a seducer (Deuteronomy 22:29); the one hundred sela paid by a defamer (Deuteronomy 22:19); all of these are paid in the sacred shekel, which is one hundred dinars in Tyrian coinage. All of the cases in which a defined amount is mentioned by the Torah have already been taught, and it is unclear what Rav Asi adds.

The Gemara answers: It was necessary for Rav Asi to teach: And any amount of money set by rabbinic law is in provincial coinage, as we did not learn that halakha in that mishna. As it is taught in a baraita: The Sages established that one who strikes another as an act of disrespect must give him one sela as a fine. And Rav Asi is teaching that one should not say: What is the meaning of one sela? It is a Tyrian sela worth four dinar. Rather, what is the meaning of one sela? This is the sela of provincial coinage, which is worth half a dinar, as people commonly call half a dinar by the name sela [isteira].

Rabbi Shimon ben Lakish says a different explanation: The reasoning of Beit Shammai, that the minimum amount with which a woman can be betrothed is one dinar, is in accordance with the opinion of Ḥizkiyya. As Ḥizkiyya says that the verse states with regard to a Hebrew maidservant: “Then he shall let her be redeemed” (Exodus 21:8), which teaches that she can deduct an amount from the price of her redemption and leave before her time of slavery is complete. If she comes into possession of money, she can pay the master for her value, less the work she has performed. Beit Shammai derive the halakhot of regular betrothal from the case of a Hebrew maidservant, as explained below.

Granted, if you say that when she was acquired he gave her at least one dinar, this is the meaning of the statement that she may continually deduct from that amount up to one peruta. But if you say that he gave her one peruta when he purchased her as a maidservant, can she deduct from one peruta? One peruta is already the smallest possible sum of money. The Gemara rejects this argument: But perhaps this is what the Merciful One is saying: In a case where he gave her one dinar, she deducts from that amount up to one peruta; in a case where he gave her one peruta she cannot deduct at all. If he paid one peruta for her, the option of redemption does not apply.
