במדבר, פרק כ״ו, פסוק כ״ד

The census in the plains of Moab establishes the lineage of the nation, firmly linking the generation preparing to enter the land with the founding fathers who originally went down to Egypt. The names recorded in this registry carry deep historical, spiritual, and family significance. For example, one individual from the tribe of Issachar is recorded with the name Yashuv, though his original name was Yov. Commentators offer two distinct explanations for this change. The first approach connects the new name to spiritual excellence, noting that this family established academies, consisted of wise men who dedicated fixed times to study, and sat as judges in courts [שפתי חכמים, קיצור בעל הטורים, משכיל לדוד]. A second approach reveals a family and religious drama. At the time, Yov was the name of a local idol, causing the son great shame and resentment over his given name. To comfort his child, his father Issachar took one of the extra letters from his own name and gave it to his son, transforming Yov into Yashuv [חזקוני, נחל קדומים, דברי דוד].

The mention of these tribal families provides an opportunity to clarify a fundamental rule of the census: Israelite families were named exclusively after the individuals who actually participated in the descent to Egypt. Those born afterward did not have families named in their honor. There were only a few rare exceptions to this rule, such as the sons of Joseph who were born in Egypt, and Ard and Naaman, the grandsons of Benjamin [רש״י].

The unique status of Benjamin's grandsons sparks a discussion among scholars. One view suggests that their mother was pregnant with them during the journey to Egypt, meaning they are conceptually viewed as having made the descent themselves, similar to the grandsons of Judah and Asher [רבי משה הדרשן המובא ברש״י, מזרחי]. Conversely, another perspective argues that their recognition was purely demographic. While Benjamin's son Bela had many grandsons, Ard and Naaman produced exceptionally massive populations. Because of their extraordinary numbers, they were granted the status of independent families, whereas the other descendants remained grouped under the family of their father, Bela [רש״י, גור אריה].

This demographic discussion sheds light on a tragedy that befell the tribe of Benjamin. Comparing the current census to the original list of those who went down to Egypt reveals that five families from the sons of Benjamin perished and are completely missing from the count. This profound loss is understood as a partial fulfillment of the prophecy made by their mother, Rachel, who in her final moments named her son Ben-Oni, meaning the son of my sorrow. Although a discussion about the tribe of Benjamin might seem out of place amid the families of Issachar, it is included here to complete a sequence of specific teachings on the census. Furthermore, it serves as a mathematical proof: if the tribe of Benjamin lost half of its founding families yet still maintained a vast population, the surviving families must have multiplied at an enormous rate. This rapid expansion perfectly justifies why descendants like Ard and Naaman needed to be divided into independent sub-families [רש״י, ברכת אשר, משכיל לדוד].
