A Judahite (1Ch 2:52). Perhaps the name should be corrected to Reaiah (cf. 1Ch 4:2).
Shobal the father of Kiriath Jearim had sons: Haroeh, half of the Menuhoth.
Reaiah the son of Shobal became the father of Jahath; and Jahath became the father of Ahumai and Lahad. These are the families of the Zorathites.
