zar.chi designates a man or group identified with Zerah’s clan in genealogical and military settings.

The term functions as a gentilicial designation for those identified with Zerah’s clan: it occurs in clan lists, in the selection of a family within Judah, and in descriptions of men assigned to military divisions.

   In Numbers 26:13 and Numbers 26:20, the masculine singular gentilic occurs in clan lists alongside Zerah, where the APB renders the clauses “the clan of the Zerahites.” In Joshua 7:17, the same form identifies the family selected from Judah, while 1 Chronicles 27:11 and 1 Chronicles 27:13 identify Sibbecai and Maharai in notices concerning their military divisions.

In the Anselm Project Bible: The APB presents the term as “the Zerahites” in the clan-list and family-selection clauses, and as “the Zerahite” in the military notices. These renderings confirm the verses’ group identification rather than supplying a separate lexical distinction.
