The word "Ketubah" comes from the root Kaf-Tav-Beit, meaning "writing." The ketubah is also called the marriage contract.
The ketubah spells out the husband's obligations to the wife during marriage, conditions of inheritance upon his death, and obligations regarding the support of children of the marriage.
To prove the rabbi wrong, the Roman woman went home and took a thousand male slaves and a thousand female slaves and matched them up in marriages.
The next day, the slaves appeared before her, one with a cracked skull, another with a broken leg, another with his eye gouged out, all asking to be released from their marriages.
According to the Talmud, Rav Yehuda taught that 40 days before a male child is conceived, a voice from heaven announces whose daughter he is going to marry, literally a match made in heaven!
In Yiddish, this perfect match is called "bashert," a word meaning fate or destiny.
Marriage agreements of this sort were commonplace in the ancient Semitic world.
