Moulton & Milligan — Vocabulary of the Greek NT
προσκαρτέρησις. The only reference for this subst. in 1,58 is Eph 618, and Thayer includes it in his ‘‘ Biblical” list. Two other exx. can, however, now be quoted from two deeds of manumission from Kertch (Panticapaeum) on the Black Sea. The earlier of these, Zatyschev II. 53!#: (a.p. 81), runs—xwpls is τὴ]ν προ[σ]ευχὴν θωπείας τε kal προσκα[ρτερ]ήσεως, ‘* besides reverence and constancy towards the place of prayer’’: see Deissmann ZAZ p. roof., and, independently, Hicks J 7S x. p. 571 f.
