Rabbi Yirmeya of Difti explains how this mishna demonstrates that one follows the majority even in cases of capital law: Why is a man who engaged in intercourse with a three-year-old girl who was married to another man liable to receive the death penalty? Say that perhaps it will turn out that she is a sexually underdeveloped woman [ailonit] who is incapable of bearing children, and her husband did not betroth her with this understanding; and consequently the marriage is null, as it was entered into in error. Therefore, a man who engaged in intercourse with her should not be liable to receive the death penalty for adultery. Rather, is it not that we say that one follows the majority, and the majority of women are not sexually underdeveloped women, and therefore the assumption is that the betrothal was valid? This is proof that even in cases of capital law one follows the majority.

The Gemara refutes this claim: No; rather, what is the meaning of that which is taught in the mishna: And if she is married, a man other than her husband is liable for engaging in intercourse with her due to violation of the prohibition against intercourse with a married woman? This means that if a man unwittingly engaged in intercourse with a three-year-old girl who was married to another man, he is liable to bring a sin-offering, but there is no liability to receive the death penalty based on a majority.

The Gemara asks: But wasn’t it taught in the mishna: And if one of any of those with whom relations are forbidden, which are enumerated in the Torah, engaged in intercourse with her, the man is executed by the court for engaging in intercourse with her? The Gemara answers: This is referring to a case where her father or some other close relative engaged in intercourse with her, so that the prohibition is incest, rather than adultery.

The Gemara asks: But wasn’t it taught: If one of any of those with whom relations are forbidden engaged in intercourse with her, the man is executed by the court for engaging in intercourse with her? This seems to indicate that the death penalty is imposed for all types of forbidden intercourse with a three-year-old girl, even if the intercourse is forbidden as a result of her being married. The Gemara refutes this claim: Rather, what are we dealing with here? With a case where the husband explicitly accepted her upon himself as his wife even if she turns out to be a sexually undeveloped woman. Therefore, another man who engages in intercourse with her is liable to receive the death penalty even if he is not one of her close relatives.

§ The Sages taught in a baraita: If a woman was acting lewdly with her minor son and he performed the initial stage of intercourse with her, Beit Shammai say that he has thereby disqualified her from marrying into the priesthood. And Beit Hillel deem her fit to marry into the priesthood, because they maintain that the intercourse of a minor is not regarded as intercourse.

Rabbi Ḥiyya, son of Rabba bar Naḥmani, says that Rav Ḥisda says, and some say that Rav Ḥisda says that Ze’eiri says: All, i.e., both Beit Shammai and Beit Hillel, concede with regard to a boy nine years and one day old that his intercourse is regarded as intercourse and disqualifies a woman from marrying into the priesthood as well as results in her liability to receive the death penalty, even though he himself is not liable to receive it. And they also all concede concerning a boy less than eight years old that his intercourse is not regarded as intercourse vis-à-vis these halakhot. They disagree only about a boy who is eight years old, as Beit Shammai maintain that we learn from earlier generations, when people were able to father children at that age, and we apply that reality to the present; and Beit Hillel maintain that we do not learn from earlier generations.

The Gemara asks: And from where do we derive that in earlier generations men fathered children at this age? If we say that we know this from the following calculation: It is written: ''Is this not Bathsheba, daughter of Eliam, wife of Uriah the Hittite?'' (II Samuel 11:3). And it is also written: ''And Eliam, son of Ahithophel the Gilonite'' (II Samuel 23:34), which teaches that Bathsheba was the granddaughter of Ahithophel. And it is written with reference to the birth of Solomon: ''And he sent by the hand of Nathan the prophet, and he called his name Jedidiah, for the Lord’s sake'' (II Samuel 12:25).

And later it is written: ''And it came to pass after two years, that Absalom had sheepshearers'' (II Samuel 13:23), and at that time Amnon was killed (see II Samuel 13:23–29), this being at least two years after Solomon was born. And afterward it is written: ''So Absalom fled, and went to Geshur, and was there three years'' (II Samuel 13:38), so that this was five years after Solomon was born.

And it is written: ''So Absalom dwelt two years in Jerusalem, and did not see the king’s face'' (II Samuel 14:28), bringing the tally to seven years after Solomon was born. And it is written: ''And it came to pass after forty years, that Absalom said to the king, I pray you, let me go and pay my vow, which I have vowed to the Lord, in Hebron'' (II Samuel 15:7). This was the beginning of Absalom’s rebellion against David. Accordingly, at that time Solomon was at least seven years old. And at some point during the rebellion it is written: ''And when Ahithophel saw that his counsel was not followed, he saddled his donkey, and arose, and went to his house, to his city, and put his household in order, and strangled himself and died'' (II Samuel 17:23).

And it is written: ''Bloody and deceitful men shall not live out half their days'' (Psalms 55:24). And in keeping with this verse, it is taught in a baraita: All of Doeg’s years were only thirty-four and Ahithophel’s were only thirty-three. Neither reached the age of thirty-five, half of the normal life span of seventy years. Based on this, one can calculate: How many years did Ahithophel live? Thirty-three. Subtract seven years, Solomon’s age at the time of Ahithophel’s death, which leaves Ahithophel twenty-six years old at the time of Solomon’s birth. Subtract two more years for three pregnancies, one preceding the birth of Eliam the son of Ahithophel, one preceding the birth of Bathsheba, daughter of Eliam, and one preceding the birth of Solomon, son of Bathsheba. It turns out that three generations were born in twenty-four years, and that each and every parent begot a child at the age of eight.

The Gemara refutes this proof: From where do you prove this? Perhaps both Ahithophel and his son Eliam fathered children when they were each nine years old, and Bathsheba gave birth to Solomon when she was six, because a woman is stronger and can conceive at an earlier age. Know that this is true that women conceive at an earlier age, as Bathsheba had already given birth to a child from David before giving birth to Solomon (see II Samuel 11:27). Therefore, no proof can be derived from here.

Rather, it is from here that one can deduce that in earlier generations men fathered children at the age of eight, as it is written: ''And these are the generations of Terah; Terah begot Abram, Nahor, and Haran'' (Genesis 11:27). And Abraham was at least one year older than Nahor, and Nahor was one year older than Haran, so it turns out that Abraham was two years older than Haran. And it is written: ''And Abram and Nahor took wives for themselves; the name of Abram’s wife was Sarai and the name of Nahor’s wife was Milka, daughter of Haran, father of Milka and father of Iscah'' (Genesis 11:29).

And Rabbi Yitzḥak says: Iscah is in fact Sarah. And why was she called Iscah? Because she envisioned [shesokha] hidden matters by means of divine inspiration. And this explains what is written: ''In all that Sarah has said to you, hearken to her voice'' (Genesis 21:12). Alternatively, Sarah was also called Iscah, because all gazed [sokhim] upon her beauty. And it is written: ''And Abraham fell upon his face, and laughed, and said in his heart: Shall a child be born to him that is a hundred years old? And shall Sarah, who is ninety years old, give birth?'' (Genesis 17:17). How much older was Abraham than Sarah? He was ten years older than her and, as stated above, he was two years older than her father, Haran. It turns out then that when Haran begot Sarah, he begot her at the age of eight.

The Gemara refutes this proof: From where do you prove this? Perhaps Abraham was the youngest of the brothers, and not the oldest among them. The fact that Abraham is listed first is no proof that he was the oldest, as perhaps the verse listed them in the order of their wisdom and therefore Abraham, being the wisest, was mentioned first.

Know that it is true that the verse sometimes lists brothers not according to their birth order, but in the order of their degrees of wisdom, as it is written: ''And Noah was five hundred years old; and Noah begot Shem, Ham, and Japheth'' (Genesis 5:32). According to this, Shem was at least one year older than Ham, and Ham one year older than Japheth, so it turns out that Shem was two years older than Japheth. And it is written: ''And Noah was six hundred years old when the flood of waters was upon the earth'' (Genesis 7:6). And it is written: ''These are the descendants of Shem; Shem was one hundred years old, and begot Arpachshad two years after the flood'' (Genesis 11:10). If Shem was the oldest brother, how could he be only 100 years old? He must have been at least 102 years old, as Noah was 500 years old when his third son was born, and he was 600 years old at the time of the flood.

Rather, the verse listed them in the order of their degrees of wisdom, Shem being the wisest. With regard to his age, Shem was the youngest of the brothers, having been born when Noah was 502 years old. Shem begot his son 100 years later, which was two years after the flood. Here too, then, with regard to the sons of Terah, it can be argued that the verse lists them in the order of their degrees of wisdom.

Rav Kahana says: I stated this discussion before Rav Zevid of Neharde’a. When he heard it, he said to me: You learn that Shem was not Noah’s oldest son from there, and we learn it from here: ''And to Shem, the father of all the children of Eber, the brother of Japheth the elder, to him also were children born'' (Genesis 10:21). This verse indicates that Japheth, rather than Shem, was the oldest of the brothers.

The Gemara asks: Rather, from where do we derive that in earlier generations men fathered children at the age of eight? From here, as it is written: ''And Bezalel, son of Uri, son of Hur, of the tribe of Judah, made all that the Lord commanded Moses'' (Exodus 38:22). And it is written: ''And Azubah died, and Caleb took for himself Ephrat, who bore him Hur. And Hur begot Uri, and Uri begot Bezalel'' (I Chronicles 2:19–20). And when Bezalel made the Tabernacle how old was he? He must have been at least thirteen years old, as it is written: ''And all the wise men that carried out all the work of the sanctuary, came every man from his work that they did'' (Exodus 36:4), and one who is less than thirteen is not called a man. And it is taught in a baraita: In the first year following the exodus from Egypt Moses made the Tabernacle; in the second year he erected the Tabernacle and sent out the spies.

And it is written that Caleb, Bezalel’s great-grandfather, said to Joshua: ''I was forty years old when Moses the servant of the Lord sent me from Kadesh Barnea to spy out the land'' (Joshua 14:7). And he added: ''And now, behold, I am this day eighty-five years old'' (Joshua 14:10). How many years old was Caleb when he was sent off with the spies? He was forty. Subtract fourteen years, as Bezalel was at least fourteen years old when Caleb was sent to spy out the land. This is known because that mission took place a year after the Tabernacle was erected. This leaves twenty-six years. Subtract two more years for three pregnancies, one preceding the birth of Hur, son of Caleb, one preceding the birth of Uri, son of Hur, and one preceding the birth of Bezalel, son of Uri. It turns out that three generations were born in twenty-four years, and that each and every parent begot a child at the age of eight.

§ The mishna teaches that the penalty for rebelliousness is imposed upon a son, but not upon a daughter. It is taught in a baraita: Rabbi Shimon says: It would be reasonable that a daughter should be fit to be treated like a stubborn and rebellious son, and to be punished like him if she sins in the same way as he does.
