(Heb. Arki', אִרְכִּי; Sept. combines with the following word, Ἀρχιαταρώθ ; 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 (Joshua 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, Genesis 10:10), elsewhere named only as the residence of Hushai the Archite (Heb. Arki', אֲרְכִּי, Sept. Ἀρχί v. r. Ἀραχί ), one of those who adhered to David during Absalom's rebellion (2 Samuel 15:32; 2 Samuel 16:16). (See ARCHITE).
This place has, with great probability, been identified with the present in Ar Ak, a small modern village with a Greek Church adjoining, laid down on the Ordnance map four and one eighth miles west of ElBireh (Conder, Tent Work, ii, 104; Tristram, Bible Places, p. 176).
