The family records of Gershon trace the exact line of his descendants, paying careful attention to his son Shimei and his children. There is a general agreement among commentators that the Shimei listed in this context is indeed Gershon's son.
Preserving these ancient family lines requires absolute precision. Within the catalog of Shimei's sons, a strict tradition governs the exact record of the name Zina. When people read or copy continuous lists of names, there is a natural tendency to accidentally attach a connecting word like "and" before a name. However, this specific name is intentionally preserved without any added conjunction. It belongs to a traditional category of words that must never be altered by adding an "and" at the beginning, ensuring the historical record remains completely accurate and protected from a very common reading error [מנחת שי].
