דברי הימים א, פרק ב׳, פסוק ל׳

Tracing a family tree often reveals branches that flourish and others that suddenly stop. The lineage of Nadav, son of Shammai, continues forward through his two sons, Seled and Appaim, but it is abruptly cut short with his oldest child. Seled passed away without leaving any sons behind [רד״ק], a status that marks a complete and total absence of male heirs [מלבי״ם].

It remains unknown whether Seled had any other descendants, such as daughters. However, the practical outcome of his passing is definitive. Without sons to carry his name into the future, it became impossible to record and continue a formal genealogical line in his honor [ביאור שטיינזלץ].
