בראשית, פרק י׳, פסוק ל״א

The conclusion of the lineage of Shem traces the gradual evolution of early human society. The progression begins with the most basic social unit, as people gathered into small family clans and tribes. Over time, these family groups developed their own distinct languages. This linguistic division naturally led to geographic dispersion, with different groups settling in various lands. Ultimately, this process reached its final stage when these scattered groups fully solidified into independent nations [ביאור שטיינזלץ].

Beyond this historical progression, the record of these generations is carefully organized around the numbers seven and twelve. The lineage tracing from Shem down to Peleg consists of exactly twelve individuals. In contrast, the subsequent branching of Arabian tribes, consisting of Joktan and his sons, totals fourteen names, forming a precise multiple of seven [קאסוטו].

A subtle detail in how these resulting nations are recorded points to a deeper theme of separation. While some ancient traditions preserve language that implies a blending among these global groups, the universally accepted tradition uses phrasing that establishes clear boundaries [מנחת שי]. This choice carries a profound underlying message regarding the future nation of Israel. It indicates that Israel is meant to remain distinct and not assimilate into the broader global population, existing as a unique, separate entity that preserves its special identity apart from the rest of the world [צפנת פענח].
