Jorkoam
[some Jorko'äm] (Hebrew Yorkeäm',יָרְקְעָ, paleness of the people, or perh. extended people Sept. Ι᾿ερκαάν v.r. Ι᾿εκλάν, both confounded with Rekem following; Vulgate Jercaam), a person apparently named as the son of Raham, of the descendants of Caleb, the brother of Jerahmeel, of the tribe of Judah (1Ch_2:44); but others (e.g. Gesenius after Jarchi) understand "father" there to mean founder, so that this would be the name of a town settled by Raham an interpretation sustained by a similar use of other names in the same connection. The locality thus alluded to is otherwise unknown, but from the associated places may be presumed to have been a place in the region southeast of Hebron.
