Tracing the ancestral line of Mahli brings a specific focus to the life of Eleazar. In the ancient tribal system, establishing a recognized, independent patriarchal household relied entirely on having male heirs. Because Eleazar did not have any sons, he was unable to form a distinct family branch of his own [מצודת דוד].
However, the lack of male heirs did not mean his family line completely disappeared. It is highly probable that Eleazar had daughters. To preserve their family bond and heritage, these daughters married their cousins, the sons of Eleazar's brother [ביאור שטיינזלץ]. Through these unions, Eleazar's descendants remained woven into the broader family structure, even without a formal household bearing his name.
