Why Divorce Must Completely Sever and the Sotah Counts as Defilement

Sifrei Devarim, the classical halakhic Midrash on Deuteronomy, holds two passages on how the structural mechanisms of separation and defilement operate through specific operational definitions. One passage records R. Elazar b. Azaryah's reading of Krithuth as something that severs completely between a man and a woman, with R. Yossi agreeing and R. Akiva arguing through structural comparison of the stricter married-woman prohibition versus the lesser divorcée prohibition that a conditional divorce that leaves any lingering loophole is not the complete severing the Torah requires. The other passage reads Deuteronomy 24's after she has been defiled in the context of remarriage, with R. Yossi b. Kipper quoting R. Elazar b. Azaryah that only cohabitation defiles so a second-stage betrothal alone leaves the woman permitted to return to her first husband, but the sages broadening the prohibition to include both betrothal and marriage and reading the after she has been defiled phrase as also including the sotah, the woman whose seclusion with a warned man constitutes structural defilement even without proven adultery.

Both passages share one structural claim. The structural mechanisms of separation and defilement operate through specific operational definitions that the midrash documents.

What it means for Krithuth to require complete severing

Sifrei Devarim's account of Krithuth opens with R. Elazar b. Azaryah offering a powerful image. He says that divorce, in Hebrew, Krithuth, is something that severs completely between a man and a woman. It is not a maybe, not a perhaps, but a definitive separation. The Aggadic tradition records R. Yossi agreeing wholeheartedly with R. Elazar b. Azaryah's view.

R. Akiva enters the debate. He poses a structural question. Why does the Torah have stricter rules about who a divorced woman can marry, specifically forbidding her to a Cohein, a priest, and about married women in general, forbidding them to all men other than their husbands? R. Akiva argues that the prohibition concerning a married woman must be more serious than the prohibition concerning a divorcée. If a divorced woman, who is under a lesser stringency, is forbidden to a Cohein, then a married woman, under a greater stringency, should certainly be forbidden to someone to whom she was once permitted, especially if her divorce is only conditional.

How a conditional divorce fails the Krithuth requirement

R. Akiva's line of reasoning implies that if a divorce is not absolute, if there is a lingering possibility of reconciliation or a legal loophole that questions its validity, then it is not Krithuth, it is not that complete severing that R. Elazar b. Azaryah emphasized. The structural reading is operational. A conditional divorce that leaves an opening is structurally not a divorce.

The Sifrei compiles this not just as legal technicalities but as the spirit of the law. When a marriage ends, it must truly end. There must be no ambiguity, no lingering attachments, no potential for future complications. The structural completeness that Krithuth requires operates as the operational threshold below which the relationship is not actually severed. The debate between these rabbis highlights the importance of clarity and finality in matters of divorce.

What it means for the sotah's seclusion to count as defilement

Sifrei Devarim's account of remarriage-defilement takes up the parallel structural picture. The passage grapples with when a woman is considered defiled in the eyes of the law, making it impossible for her to remarry her first husband after a divorce and subsequent marriage. The text states that after she had been defiled refers to the period after the first marriage until after the second marriage. The rabbis dig deeper. What about the period between kiddushin and nissuin? What if the second relationship only reached the stage of betrothal? What if it went from marriage to betrothal? Or betrothal to betrothal?

The text gives a lifeline. Her first husband shall not be able to take her, her first to take her, who had sent her away to take her, to return to take her. This repetition broadens the scope of the law. It suggests that the prohibition against remarriage applies not only to cases of full marriage, but also to situations involving betrothal.

How R. Yossi b. Kipper and the sages divide on betrothal-as-defilement

Rabbi Yossi b. Kipper, quoting Rabbi Elazar b. Azaryah, offers a dissenting opinion. He argues that if the second relationship only reached the stage of betrothal, the woman is permitted to return to her first husband. His reasoning is operational. The phrase after she has been defiled implies cohabitation, sexual relations. Without that, there is no defilement.

The sages disagree. They maintain that both betrothal and marriage in the second relationship make it impossible for the woman to return to her first husband. So why the phrase after she has been defiled? The structural answer is to include the case of a sotah, a woman suspected of adultery who has secluded herself with the man she was warned against. Even without proof of actual adultery, the very act of seclusion raises suspicion. According to the sages, this situation, where a woman has placed herself in a compromising position, also constitutes defilement in the eyes of the law, preventing her from remarrying her first husband. The structural broadening of defilement beyond the physical act is operational.

How Krithuth-severing and sotah-defilement share one structural principle

The two passages converge on the same kind of structural operational definition. The structural mechanisms of separation and defilement operate through specific operational definitions. Krithuth requires complete severing, with R. Akiva's reasoning showing that any conditional divorce fails the structural threshold. After she has been defiled includes both the sages' broader reading of betrothal-as-defilement and the sotah's seclusion-as-defilement, with R. Yossi b. Kipper's narrower cohabitation-only reading rejected. Both situations show that the cosmic system tracks both severing and defilement through specific operational thresholds rather than through vague spectrums.

The Sifrei Devarim tradition teaches the reader that they encounter the same structural operational definitions in their own relationships and seclusions. The two passages close with a composite image. A divorce whose Krithuth either completely severs or, if conditional, fails to sever at all, with R. Akiva's qal va-chomer setting the structural threshold. A remarriage prohibition whose after she has been defiled extends through betrothal and even through the sotah's seclusion alone, with R. Yossi b. Kipper's cohabitation-only reading overruled by the sages' broader structural reading. A reader, situated within their own separations and seclusions, recognizing that the cosmic system tracks both with the operational precision the midrash documents.
