דברי הימים א, פרק ב׳, פסוק כ׳

A brief family tree traces the lineage of one of the most central figures in Israelite history, revealing a highly unique timeline. The record leads directly to Bezalel, the chief architect of the Tabernacle. Because of his vital role and high status, he is explicitly named in a family line where many other descendants are completely left out [ביאור שטיינזלץ].

Beyond identifying a famous builder, this family record presents an unusual chronological phenomenon regarding the age of fatherhood. A surprising pace of generations emerges when examining the age of Caleb, the father of Hur, during the incident of the spies, alongside the fact that his descendant Bezalel was already an adult working on the Tabernacle at that same time. Historical calculations show that each father in this specific family line had his son when he was less than eight years old. There is even a tradition indicating that these fathers had sons as early as six years of age [רש״י].
