The historical records of the tribe of Ephraim resume their natural course after a brief story about the men of Gath. The main purpose of this family record is to carefully trace the exact lineage leading down to Joshua the son of Nun [רד״ק, רלב״ג, מלבי״ם].
Tracing this specific family tree presents a challenge, as there are different ways to understand the relationships between the generations. The primary approach among commentators is that Rephah is the son of Beriah, who was introduced just before this point [רש״י, מצודת דוד]. Following this branch, the family line continues with Resheph and Telah, who are both understood to be the sons of Rephah [רש״י, מצודת דוד]. Tahan is then identified as the son of Telah [מצודת דוד, רלב״ג]. However, other perspectives suggest different family dynamics. One view proposes that Rephah and Resheph were actually brothers, with Telah being the son of Rephah, and Tahan the son of Telah [רלב״ג]. Taking a completely different approach, another perspective argues that these four men do not represent a chain of fathers and sons at all. Instead, they are all brothers, the sons of Beriah. This is supported by the way their names are linked together in the record, which implies a parallel group of siblings rather than a descending lineage [מלבי״ם].
Ultimately, this family tree moves forward to Elishama the son of Ammihud, and finally to Joshua. The timeline of this specific lineage aligns well with an ancient tradition regarding the tribe of Ephraim. According to this tradition, the descendants of Ephraim made an early attempt to leave Egypt, an event that occurred even before the actual period of Egyptian enslavement began [מלבי״ם].
