Ar'chi (Heb. Arki', אִרכִּי; Sept. combines with the following word, Α᾿ρχιαταρώθ; Vulg. Archi Ataroth; but the Hebrews has no connective between the words, where the Auth. Vers. has prob. supplied the best relation "to"), a city or place on the boundary of Benjamin and Ephraim, between Bethel and Ataroth (Jos 16:2); supposed by some to be the region of Beni-Zeid (Keil, Comment. in loc.), which, however, is too far north SEE ATAROTH, and rather to be sought in the valley west of Bethel, perhaps at the ruined site called Kefr Musr. SEE TRIBE. It appears to designate (collectively used) a clan inhabiting a district called Erech (different, of course, from that in Babylonia, Ge 10:10), elsewhere named only as the residence of Hushai the Archite (Heb. Arki', אֲרכִּי, Sept. Α᾿ρχί v. r. Α᾿ραχί), one of those who adhered to David during Absalom's rebellion (2Sa 15:32; 2Sa 16:16). SEE ARCHITE.
