1 Chronicles 4:2

“And Reaiah the son of Shobal begat Jahath, etc.] Reaiah is the same with Haroeh, (<130252>1 Chronicles 2:52) the names are of the same signification: and Jahath begat Ahumai, and Lahad. These are the families of the Zorathites; who inhabited Zoreah, as the Targum, at least part of it; (see <130253> 1 Chronicles 2:53,54).”

“Reaiah: Ch1 2:52, Haroeh Zorathites: Ch1 2:53, Ch1 2:54; Jos 15:33; Jdg 13:25 1 Chronicles 4:3”

“Ch1 4:2, with the descendants of Shobal. As to Reaiah the son of Shobal, see Ch1 2:52. He begat Jahath, a name often occurring in Levite families, cf. Ch1 6:5, Ch1 6:28; Ch1 23:10., Ch1 24:22, Ch2 34:12; but of the descendant of David who bore this name nothing further is known. His sons Ahumai and Lahad founded the families of the Zorathites, i.e., the inhabitants of Zora, who also, according to Ch1 2:53, were descended from sons of Shobal. Our verse therefore gives more detailed information regarding the lineage of these families. 1 Chronicles 4:3”
