דברי הימים א, פרק ד׳, פסוק י״א

Genealogical records in the Book of Chronicles often introduce new family branches suddenly, leaving out the connecting links to previous generations. Two brothers, Kelub and Shuhah, abruptly appear in the historical record in this manner, having never been mentioned before. The primary approach among commentators is that this sudden introduction reflects the concise style of the book, which frequently lists individuals and their descendants without detailing their complete lineage or naming their fathers. A historical explanation for this pattern suggests that the author originally drew from a much older, highly detailed genealogical record. However, rather than transcribing every name, the author deliberately skipped over generations of people who did not stand out. By choosing to record only the names of distinguished and important figures, the narrative jumps directly to Kelub [מלבי״ם].

On the other hand, an alternative perspective suggests that Kelub and Shuhah were indeed mentioned earlier in the family trees, but were simply recorded under different names [מצודת דוד]. Building on this idea, Shuhah is specifically identified with Hushah, a figure mentioned earlier as the son of Ezer. Following this logic, it is concluded that Kelub was also actually a son of Ezer [רלב״ג].
