What I read an author state is the primary reason for the practice of child marriage among both Jews and Muslims was to ensure chastity. Yemen has a very conservative society, that is true of the Muslims, that was true of their Jewish community, as well.
You need to read my source again, what they said, you seem to have a problem reading and comprehending English.
Anyone can see, from going to your post earlier in this thread, that the one author stated as you quoted:
"The Yemenite girl was often engaged to be married before she was twelve years old, and she was not able to choose her future husband.
When young children were orphaned, there was a danger that the Yemenis might force their conversion to Islam and remove them from the Jewish community. Thus, marriages of very young people were often arranged to prevent this tragedy. However, it appears that young girls lived with their husbands only after they matured. Marriage to older men was not unknown, and neither was polygamy. The major circumstance leading to polygamy was the practice of*levirate marriage*(a religious obligation to marry the wife of a brother who died without issue), which was encouraged among Yemenite Jews even into the twentieth century. Following her wedding, the bride moved to her mother-in-lawÂ’s house where she joined the pool of female workers, continuing the same arduous tasks that she had been trained for by her own mother."

A few posts later you 'quoted' another author.
"The custom of child marriage, which was generally prevalent among Jews in Yemen, was not known in Aden. As Gamliel, a Yeminite writer points out, sons, particularly daughters, were married off in their early teens, in many cases even at the age of nine or ten. The marriage prospect for girls who passed the age of 18, he notes, were slim. These old girls would under the best possible circumstances be married off to a widower, a divorcee, or as a second wife. This custom of marriage at a tender age , which was similar to that of the Muslims, was essentially meant to ensure pre-marital chastity...."

The quote is found on p.126, in a lengthy footnote , which reads in full:

This custom of marriage at a tender age , which was similar to that of the Muslims, was essentially meant to ensure pre-marital chastity.
For the Yemenite Jews, however, one major motivation for child betrothal and marriage was to ensure the exemption of Jewish children from the decree of forced conversion, to which Jewish orphans who did not attain puberty before their father died were subjected in Yemen "
Evidently it is you who lacks reading comprehension. As I've already explained, when it's all one paragraph, it's all one concept.
What kind of 'scholarship' is it to cite an author and then edit out what he states is a
MAJOR MOTIVATION for the pattern he's discussing?
Once again, you have lied and the proof is here for all to read.
Stop lying, can you possibly tell the truth?
I provided a quote of a source who stated child marriage was the custom in Yemen, the fact they are the custom is the primary explanation for child marriages occurring in Yemen, and the author explains a primary purpose of this custom, ensuring chastity. Then, after stating this, he adds, "one major motivation" for Jewish children of child marriages is to protect Jewish children from the decree of forced conversion that he says would occur if the children became orphans before marriage (that would only apply if the child's parents both died before the child was married). Let's look at the sequence of the words. First, CUSTOM explains the practice, that is custom inside Yemen where child marriages are commonly embraced. Second, he tries to explain the reason for the custom. He says the custom was "essentially meant to ensure chastity." That is a primary purpose of the custom, a primary purpose of the custom for Jews and Muslims, for everyone. Third, the author lists another primary purpose of the custom for Jews he says "one primary motivation" for Jews is the concern of coerced conversions in the case the child might lose both parents before marriage and become an orphan.
Sherri why do you keep screwing up your own citations I doubt that the author
wrote----"that would only apply if the child's parents BOTH died before the child was
married. If he did------you found the wrong guy to cite. In islamic law a child
is an orphan with the LOSS OF HIS OR HER FATHER My mother-in-law lost her
father at age 11---------her MOTHER lived on -------and she did get to see her
again more than 15 years after she fled with her little husband and her
father-in-law. The reason she married at age 12 had nothing to do with chastity---
it was all ---the DHIMMI ORPHAN LAW. Yemeni muslims clung so tenaciously to the DHIMMI ---ORPHAN LAW yemenite jews managed to
create all kinds of QUICKIE ways to get an orphaned boy or girl married and
ELSEWHERE Sometimes the marriages were to unlikely candidates based
on the EMERGENCY situation The good news is that hubby's parents were
very well matched. Generally jews do not actually "marry" before the age of
consent 12 1/2 for girls and 13 for boys-----no matter how dire the circumstances---
but they can do the BETROTHAL THING ---which is a kind of binding contract
before that time. ------parents can do it for them---BOTH of them
IN fact your very own citations conform with that fact-----some rabbi marrying girls as
young as 12 and boys as young as 13--------yup-----that is possible that he wanted to
do that even though it is illegal in Israel-----Juliet was 14 when she married romeo
Kids can legally marry in Maryland USA at that age too. My mother's paternal
grandmother INSISTED on marriage at age 14 to the love of her life and proceeded
to have 10 kids in nine years--------an obvious marriage of love (then her husband
died of a war would in the army of Emperor Franz Josef-----short of age 30
what has all this got to do with the forced bedding of an 8 year old girl by a man of
40?. If her husband was 10 years old------she would be alive today

The first part is the*Mishnah*(Hebrew: משנה, c. 200 CE), the written compendium of Judaism's*Oral Torah*(Torah meaning "Instruction", "Teaching" in Hebrew). The second part is theGemara*(c. 500 CE), an elucidation of the Mishnah and related*Tannaiticwritings that often ventures onto other subjects and expounds broadly on the*Jewish Bible.
