Halfabo nope, that is not what that particular book said.
"There is even less evidence regarding female age at marriage. As noted, the overwhelming impression givin in the legal sources is that father betrothed their daughters while they were still minors. Without doubt, this happened. We do not know, however, how often it happened."
And the part I quoted comes directly after what you just quoted. Your quote says they have an "impression" of this happening, not evidence of it happening. What I quoted from your source said they had no evidence of it happening. So, yeah that is what it said.
I guess you didn't get the part that that particular book was a person trying to dismiss the notion that this was a Hebrew practice. That is fine, I'll just go straight to the Babylonian Talmud.
In Sex with Children by Talmud Rules, (34) we learned that under Talmud law, grown men may have sexual intercourse with children. Sex with girls younger than three years old is specifically permitted. We learned that the little girls are wounded and bleed as a result. Little girls may bleed after each copulation. The Sages teach that the repeated bleeding is the result of the hymen growing back and being newly ruptured with each copulation. We learned that Jewish law permits male homosexuality if the passive partner is younger than nine years old, and that homosexuality between adult men is punishable by death. We wondered how these laws could be integrated into the present system of American law and custom.
(Now we know where the Catholic Priests got it from)
Talmud Permits Child-Adult Sex
Talmud law permits sexual intercourse between children and adults. This doctrine is contained in a number of Mishnahs. Before we examine them, however, it is necessary that the reader be familiar with the word kethubah.
According to the Soncino Talmud Glossary:
KETHUBAH (Lit., 'a written [document]'); (a) a wife's marriage settlement which she is entitled to recover on her being divorced or on the death of her husband. The minimum settlement for a virgin is two hundred zuz, and for a widow remarrying one hundred zuz; (b) the marriage contract specifying the mutual obligations between husband and wife and containing the amount of the endowment and any other special financial obligations assumed by the husband.
— Babylonian Talmud, Soncino Talmud Glossary
Zuz is a unit of currency. We see, then, that a dollar (or zuz) value is put on virginity.
Now let's look at a Mishnah from Kethuboth 11a:
MISHNAH. WHEN A GROWN-UP MAN (7) HAS HAD SEXUAL INTERCOURSE WITH (8) A LITTLE GIRL, (9) OR WHEN A SMALL BOY (10) HAS INTERCOURSE WITH A GROWN-UP WOMAN, OR [WHEN A GIRL WAS ACCIDENTALLY] INJURED BY A PIECE OF WOOD (11) — [IN ALL THESE CASES] THEIR KETHUBAH IS TWO HUNDRED [ZUZ] …
— Babylonian Talmud, Tractate Kethuboth 11a
Soncino 1961 Edition, page 57
The translator, Rabbi Dr. Samuel Daiches, amplifies the text with footnotes:
7. A man who was of age.
8. Lit., 'who came on'.
9. Less than three years old.
10. Less than nine years of age.
11. Lit., 'One who was injured by wood', as a result of which she injured the hymen.
— Rabbi Dr. Daiches
Let's review the above-cited Mishnah: "When a grown-up man has had sexual intercourse with a little girl, or when a small boy has intercourse with a grown-up woman …" It is obvious that sex activity between a grown man and a little girl, and between a grown woman and a little boy, is a part of the woof and the warp of everyday Talmud life; such relationships, in the eyes of the Sages, are unremarkable. There is no prohibition on sexual activity between adults and young children — it is simply regulated. Recall the words of the Very Reverend the Chief Rabbi of the British Empire the late Dr. Joseph Herman Hertz:
Religion in the Talmud attempts to penetrate the whole of human life with the sense of law and right. Nothing human is in its eyes mean or trivial; everything is regulated and sanctified by religion. Religious precept and duty accompany man from his earliest years to the grave and beyond it. They guide his desires and actions at every moment.
— Rabbi Dr. Hertz (38)
Thus, if the Talmud permits girls three years old and younger to be sexually used by adults, that is the law. The concern of the Sages is to ensure that the adult is not, technically speaking, in violation of any of the rules.
There you go...these are the laws from which the Torah, the first five books of the "christian" Bible come from. Read it and weep, I know I did.
