Adultery
Ex. Law #129: "If the wife of a man has been caught lying with another man, they shall bind them and throw them into the waters. If the owner of the wife would save his wife then in turn the king could save his servant."
Modern English isn't all that much better, comparatively either. Husband etymology comes from "house-holder" or "house-steward". There's definitely still an implied control relationship if not necessarily "ownership".
(Contrast to Old English's companion to wif [wife], wer was simply "married man" by way of connotation change from old German wer which was simply "man".)
husband (n.)
Old English husbonda "male head of a household, master of a house, householder," probably from Old Norse husbondi "master of the house," literally "house-dweller," from hus "house" (see house (n.)) + bondi "householder, dweller, freeholder, peasant," from buandi, present participle of bua "to dwell" (from PIE root bheue- "to be, exist, grow," and compare bond (adj.)). Beginning late 13c. it replaced Old English wer as "married man (in relation to his wife)" and became the companion word of wife, a sad loss for English poetry. Slang shortening hubby first attested 1680s.
I would interpret this as the king being allowed to pardon the citizen who committed the adultery, if the husband chooses to forgive his wife.
I actually like the law. While it does still display an asymmetry of power in the relationship, it implements a negative incentive for cheating for both men and women. This is progress compared to a more primitive law that one could imagine where women could be punished arbitrarily, e.g. to death, while the man in the cheating act could not be punished by law.
Also, it seems better than vigilante justice. It gives both parties in the decision making the opportunity to show empathy, and so acknowledge the adultery without explicit punishment.
It's hard to grasp that old "bad" laws could still be very progressive.
I remember a teacher telling us that "an eye for an eye" should be viewed not as a crazy excessive response, but as a very modern "the punishment should be commensurate to the crime", which was not a given.
Likely that the king owns every man and losing manpower sucks, so if the husband wants to save his wife, the king can choose to save his servant who committed adultery.
It's a profound and highly recommended read, especially considering the sheer amount of downtime that's available at the moment.
