Moulton & Milligan — Vocabulary of the Greek NT
ἀπαράβατος. In P Ryl II. 6518 (B. C. 67?—in any case Ptol.) a judgement ends with kal τἄλλα τὰ δι᾽ αὐτῆ[ς δι]ωρισμένα μένειν κύρια καὶ ἀπαράβατα, “valid and inviolate” (Edd.). The legal formula, thus established for an early period, survives six centuries later in P Grenf I. 607 (a,D. 581) ἀπαραβάτῳ > , ἀπαρτισμος πράσει : “inviolable” must be the sense, though the words follow a hiatus. Another example, also vi/A.p., is in P Lond rors (=III. p. 257) ἄτρωτα καὶ ἀσάλευτα καὶ ἀπαράβατα[. . . , a contract for the surrender of property. See also P Catt γεείου. 19. (ii/A.p.) (= Chrest. II. p. 422) ἔνια ἀπαράβατά ἐστιν, “es gibt Dinge, an denen sich nichts andern lasst” (Ed.). It is clear that the technical use, compared with the late literary (@f. Lobeck Phryn. p. 313), constitutes a very strong case against the rendering “ not transferable”. Phrynichus himself prescribed ἀπαραίτητος : what sense that would have made in Heb 7*4 passes comprehension. Vettius Valens has the adverb five times (see index), always as “‘ validly” or “inevitably.” It occurs in P Strass 1. 405 (A.D. 569), rendered ‘‘unverbriichlich ” (Ed.).
