Arba was an ancestral figure associated with Hebron and the Anakim and is identified as the father or forefather of Anak.
Biography
Joshua refers to Hebron's earlier name as Kiriath-arba and associates Arba with the Anakim. Joshua 15:13 calls Arba the father of Anak, while other wording describes him as a great man among the Anakim. Scripture provides no independent narrative of his life.
Biblical Significance
Arba is significant chiefly for the genealogy and geography of the Anakim and for the older name of Hebron. The biblical evidence supports only a limited ancestral description.
