Moulton & Milligan — Vocabulary of the Greek NT
ἅρπαξ. Deissmann (1.4.8 p. 321 π ἢ) notes that ἅ. was current as a loan-word in Latin comedy: in Paul ‘‘it should probably not be translated ‘robber’ but rendered by some other word like ‘swindler’ (‘ extortioner,’ AV, RV).” ἀρραβών. / A word of undoubted Semitic origin (Ileb. pay, cf. Lagarde A/ittei/, I. p. 212, Lewy Hremdwirter p. 120), spelt ἀρραβών and ἀραβών : see Pro/eg. p. 45 and Thackeray Gr. I. p. 119, and cf. P Lond 3341" * (a.p. 166) (=II. p- 211 f.), where both forms occur. The meaning of ‘*earnest-money” (Scoftice ‘‘arles”’) is well illustrated by P Par 581 (ii/B.c.) (= Witkowski 3, p. 81), where a woman who was selling a cow received 1000 drachmas as ἀραβῶνα. Similarly P Lond 143}5 (a.D. 97) (ΞΞ 11. p. 204), a receipt for 160 drachmas, being the residue of the earnest-money (200 drachmas) for 234, arourae of land, ἀπὸ λόγου appaβῶνος κλήρου κτλ., P Fay gt! (A.D. 99) ἀργυρίου Spax [pds] ϑέκα ἕξ appaBova ἀναπόριφον, “τό drachmae of silver as unexceptionable earnest-money” (Edd.), P Oxy II. 2995’: (late i/A.D.) Λάμπωνι μνυοθηρευτῇ ἔδωκα αὐτῷ διὰ σοῦ ἀραβῶνα (δραχμὰς) ἢ ἵνα μυοθηρεύσει ἔντοκα, “‘regarding Lampon the mouse-catcher I paid him for you as earnest money 8 drachmae in order that he may catch the mice while they are with young” (Edd.), 2. VI. 920%? (ii/iii 4.D.) is Ady(ov) apaBa(vos) στρουτί(οῦ) (“ostrich”) (δραχμαὶ) iB, Syll 2263 (Olbia, iii/B.c.) ἐνέγκας εἰς τὴν ἐκλησίαν χρυσοῦς πεντακοσίους εἰς τοὺς ἀρραβῶνας. Additional examples are Ostr 1168, P Magd 26° (B.c. 217), P Lond 12290}5 (Α.Ὁ. 145) (=III. p. 143), 2d. 1170 verso 1533 (A.D. 258-9) (= III. p- 196), BGU I. 2408 (ii/a.p.), 26. 11. 601" (ii/A.D.), and P Grenf II. 6717 © (a.D. 237) (= Se/ectzons, p. 109) where in the engagement of certain dancing girls for a village festival provision is made that they are to receive so many drachmas ὑπὲρ ἀραβῶνος [τῇ τ]ιμῇ ἐλλογουμέν[ο]υν, “by way of earnest-money to be reckoned in the price.” The above vernacular usage amply confirms the NT sense of an “earnest,” or a part given in advance of what will be bestowed fully afterwards, in 2 Cor 1%", 5°, Eph 14 It may be added that in MGr ἡ ἀρραβωνι(α)σμένη = “the betrothed bride,” ‘‘an interesting reminiscence,” as Abbott (Songs, p. 258) remarks, ‘‘of the ancient custom of purchasing a wife.” In the same way ἥ ἀρραβῶνα is used for ‘the engagement-ring.” In the island of Cyprus we find the form ἀραῶνα (Thumb e//e7., p. 23).
