μεσότοιχον [page 400]
A parallel to this ἅπ . εἰρ . = partition-wall ( Eph_2:14 ) may be found perhaps in a fragmentary list of abstracts of contracts regarding sales of house property at Hermopolis, P Amh II. 98 .9 (ii/iii A.D.) (ἥμισυ ) μέρ (ος ) [τῶν ] μεσοτύχ (ων ?), where the editors propose to read μεσοτοίχων from μεσότοιχος (see LS). For ὁ μεσότοιχος see also an inscr. from Argos, BCH xxxiii. (1909) p. 452, No. 22 .16 .
