Moulton & Milligan — Vocabulary of the Greek NT
γνήσιος. The primary sense, ‘* born in wedlock,” is overshadowed by derived applications, but it survives in occasional formulae : thus even P Flor III. 294? (iv/a.p.) (see p. ix.) has καὶ γνησίων τέκνων σποίρᾷ ina marriage contract. In the earliest dated Greek papyrus, P Eleph τὸ (B.c. 311-10) (= Selections, p. 2), a marriage contract begins λαμβάνει “Ἡρακλείδης Δημητρίαν Κώιαν γυναῖκα γνησίαν, ‘as his lawful wedded wife”: cf. PSI I. 644 (Ὁ 1.8.6.) where a woman promises a man to live with him as long as he lives, ὡς γνησ[ία)] γαμετή, and P Oxy X. 1267%% (a.p. 209) τοῦ Zathov γνήσιον υἱὸν ‘Qpelwva, “Zoilus’ legitimate son Horion.” In P Amh II. 86% (a.p. 78) we have χωρὶς
