במדבר, פרק כ״ו, פסוק ל״א

As the census of the Israelites progresses, the counting specifically identifies the families belonging to Asriel and Shechem [ביאור שטיינזלץ].

The preservation of these names relies on a strict adherence to an exact, ancient tradition of reading and writing. Careful attention is paid to the precise pronunciation and spelling of the family of Asriel. Exact books and early traditions dictate the specific letters used when recording the individual name versus the broader family name, ensuring the historical records remain completely accurate [מנחת שי].
