Комментарий о цитате к Бамидбар 5:27

ובאו ובאו – both of them (Numbers 5:22 and Numbers 5:27) have an extra [letter] “vav” for interpretation.

נטמאה ונטמאה – (Numbers 5:27 and Numbers 5:29) the extra “vav” in the second word "ונטמאה" –and defiles herself (Numbers 5:29) is for interpretation.

Just as she is prohibited to the husband so is she prohibited to the lover, as it is said, “defiled … and is defiled” (Numbers 5:27, 29), the words of Rabbi Akiba. Rabbi Joshua said: thus Zechariah ben Hakatzav used to expound. Rabbi says: twice in the portion, “If she is defiled…defiled”--one referring [to her being prohibited] to the husband and the other to the paramour. The mishnah now moves from the midrashic idea that the waters check the suspected adulterer, just as they check the suspected adulteress, to a more normative halakhic statement. In many cases which were discussed above, the mishnah ruled that the woman is forbidden to return to her husband. This would include all cases where, for whatever reason, she doesn’t end up drinking the water. Our mishnah teaches that if she is prohibited to her husband, she is likewise prohibited to the suspected adulterer. She may not be divorced and then marry her lover, for in that way she and he would benefit from the adultery. Adultery, according to Jewish law, can never lead to marriage. Rabbi Akiva learns this ruling from the extra “and” in the second appearance of the word “defiled.” Rabbi Joshua says that Zechariah ben Hakatzav also used to expound the extra “and” in this manner. Rabbi [Judah Hanasi] suggests a different midrashic means by which to get the same result, and that is the repetition of the phrase “if she is defiled.” There is a dispute among these rabbis how to derive this law from the Torah. There is no dispute, however, about the law itself.

And on account of what is she defiled - what brought her to the point of becoming defiled? Levity and frivolity. This is to chastise the women, not to behave frivolously with men, because it is through this that they come to "her belly shall distend" [Numbers 5:27].

והתברכו בזרעך AND IN THY SEED SHALL BLESS THEMSELVES — A man will say to his son, “May your seed be as the seed of Isaac”. Such is the meaning of this phrase wherever it occurs in the entire Scriptures. The following passage is that from which this meaning may be derived for all such passages: (48:20) “By thee shall all Israel bless their children saying, “May God make thee [as Ephraim and Manasseh]”. So, too, in the case of a curse do we find a similar idea: (Numbers 5:27) “And the woman shall become a curse”, meaning that one who curses his enemy will say “May you be like such and such a woman”. Similar, also, is (Isaiah 65:15) “And ye shall leave your name for a curse unto mine elect”, meaning that one who takes an oath will say “May I be like such-and-such a person if I have really done so-and-so”.
