Ketubot 11A

אף אנו נאמר: ״איילונית״⁠ — דוכרנית, דלא ילדה.

We too will say: Ailonit, a sexually underdeveloped woman, is a term meaning: Like a ram [dukhranit], because like a male sheep [ayyil] she does not bear children.

מתני׳ הגיורת והשבויה והשפחה שנפדו ושנתגיירו ושנשתחררו, פחותות מבנות שלש שנים ויום אחד ⁠— כתובתן מאתים. ויש להן טענת בתולין.

Mishnah: With regard to a female convert, or a captive woman, or a female slave, who were ransomed with regard to the captive, or who converted with regard to the convert, or who was freed with regard to the female slave, when she was less than 3 years and one day old, for all of these, their marriage contract is 200 dinars, as their presumptive status is that of a virgin. Even if they were subject to sex when they were younger than that age, the hymen remains restored. And they are subject to a claim concerning their virginity.

גמ׳ אמר רב הונא: גר קטן ⁠— מטבילין אותו על דעת בית דין.

Talmud: Rav Huna said: With regard to a convert who is a minor, one immerses him in a mikveh with the consent of the court. As a minor lacks the capacity to make halakhic decisions, the court is authorized to make those decisions in his stead.

מאי קא משמע לן ⁠— דזכות הוא לו, וזכין לאדם שלא בפניו? תנינא: זכין לאדם שלא בפניו, ואין חבין לאדם שלא בפניו!

What is Rav Huna coming to teach us? Is he teaching that it is a privilege for the minor to convert, and one may act in a person’s interests even in his absence? We already learned that explicitly in a Mishnah (Eiruvin 81b): One may act in a person’s interests in his absence, but one may not act against a person’s interests in his absence.

מהו דתימא: גוי בהפקירא ניחא ליה, דהא קיימא לן דעבד ודאי בהפקירא ניחא ליה,

Rav Huna’s statement was necessary lest you say: With regard to a non-Jew, licentiousness is preferable for him, so conversion is contrary to his interests, just as we maintain that with regard to a slave, licentiousness is certainly preferable. Just as a slave has no interest in assuming the restrictions that come with freedom, in that a freed Canaanite slave is a convert to Judaism, a non-Jew would have the same attitude toward conversion.
