Historical Background
No district called Jerah has been securely identified. Proposed associations include places in Yemen and the Hijaz, as well as regions whose Arabic names refer to the moon. Moon worship in southern Arabia helped make the term common in place-names.

<p>je'-ra (yerach): A son of Joktan (Ge 10:26 parallel 1Ch 1:20). No district Jerah has been discovered. However, Yurakh in Yemen and Yarach in Hijaz are places named by the Arabic geographers. The fact that the word in Hebrew means "moon" has led to the following suggestions: the Banu Hilal ("sons of the new moon") in the North of Yemen; Ghubb el-Qamar ("the bay of the moon"), Jebel el-Qamar ("the mountains of the moon") in Eastern Chadramant. But in Southern Arabia worship of the moon has caused the word to bulk largely in place-names.</p>
