This week’s Torah discussion uses Balaam’s reaction to Israel’s camp to examine the rabbinic rule of "hezek re’iyah," the harm caused by being able to look into another person’s space. The article begins with Balaam seeing that the Israelites did not align their tent openings opposite one another, a sign of modesty. The Talmud in Bava Batra 60a links that detail to the question of whether one may look into a neighbor’s property and whether such visual exposure is legally actionable.
The Talmud presents two basic positions. One view holds that a courtyard partition is optional unless both neighbors agree, which would mean visual intrusion in a shared courtyard is not legally considered damage in every case. Even under that view, however, looking directly into a neighbor’s house, or harming crops and produce by staring into a field, can still count as damage. The other view says a courtyard wall is mandatory because hezek re’iyah does count as real harm. The Shulchan Aruch rules that it is indeed damage, so a neighbor can be compelled to pay for a dividing wall.
The article then reviews what happens if years pass without a wall. The Rosh and Rambam say the neighbors may have waived their claim, so they can no longer force participation in the cost. The Ramban disagrees, arguing that this is an issue of prohibition, and prohibitions cannot be waived. A third approach, attributed to the Yad Ramah, is intermediate: in some cases a shared wall can still become subject to waiver or legal presumption, especially when a window opposite a window does not necessarily produce constant viewing.
In practice, the Shulchan Aruch and Rema are presented as partially diverging, and the article notes an important limit: a window facing a courtyard is different from a window facing another window inside a home, where privacy concerns are stronger. Modern cities also challenge the classic rule, since many buildings have facing windows. One explanation allows this because today windows are often covered by curtains or shutters, and doors are usually closed; another says local custom matters, so where people do not object, there is no actionable damage.
The final section turns to wiretapping. A rabbinic court case about a husband recording his wife during divorce proceedings suggests that hezek shmi’ah, harm caused by hearing, was not directly addressed in the Talmud. The Mairi is cited as implying listening harm is not generally a concern in a courtyard because people watch what they say, while the Ra’ah is cited as saying there is no such category at all. The court concluded that even if secret recording may raise halakhic or moral concerns in principle, once the recording has already been made, it can be used after the fact as evidence.
