דברי הימים א, פרק ב׳, פסוק כ״ב

Tracing a person's family tree and how they acquired their land often reveals complex historical connections. The lineage of Jair and his inheritance in the land of Gilead present an interesting puzzle regarding his true tribal identity. Detailed genealogical records help bridge the gaps between various historical accounts to clarify this mystery.

The primary approach among commentators is that this individual is the exact same Jair mentioned in the books of Numbers and Deuteronomy, famous for conquering cities in Gilead and naming them after himself. A notable tension exists because earlier records refer to him as a descendant of Manasseh, while his official paternal line actually traces back to the tribe of Judah. The connection to Manasseh stems entirely from his mother's family, as his grandmother was the daughter of Machir, the son of Manasseh. When Machir set out to conquer the region of Gilead, Jair accompanied him. During this campaign, Jair captured his own territory and chose to remain there with his maternal relatives, firmly establishing those cities as his personal inheritance [רד״ק, ביאור שטיינזלץ].

In contrast, a tradition from the sages suggests a completely different background. According to this perspective, the individual mentioned here is not the famous Jair from the earlier accounts, but rather a different man altogether. Instead of gaining his territory through military conquest, this Jair, the son of Segub, acquired his land through marriage. He married a woman from the land of Gilead, and upon her death, he inherited her estate. It was through this inheritance, rather than battle, that the twenty-three cities in the region fell into his possession [רד״ק, מצודת דוד].
