Conditional birth estimate
Conditional birth bounds under generation assumptions; not attested parental ages, biological limits or a lifespan.
The anchors give incompatible conditional intervals. This calculation establishes no birth year.
Below are relatives with a selected birth year, the generations separating them, and the interval allowed by each anchor. Each relative’s page shows available dates and sources. The overall estimate uses the intersection of the allowed intervals.

Jerah is mentioned in the Table of Nations in Genesis and 1 Chronicles as one of the sons of Joktan, a descendant of Shem, the son of Noah. Joktan's descendants are believed to have settled in the southern Arabian Peninsula, suggesting that Jerah and his brothers may have been associated with the ancient peoples of that region. However, no further details are provided about Jerah's life or the specific territory he and his descendants inhabited.
