Moulton & Milligan — Vocabulary of the Greek NT
ἀσθενέω is too common to need many citations. There is a pathetically laconic ᾿Ασθενῶ between some household details and concluding salutations in an undated letter, BGU III. 82774 P Oxy IV. 725% (A.D. 183) is typical: a boy apprenticed to a weaver is to have 20 holidays a year for festivals, without loss of wages, ἐὰν δὲ πλείονας τούτων ἀργήστ [ἢ ἀσ]θενήσῃ ἢ ἀτακτήσῃ κτλ, “from idleness or ill-health or disobedience’ (Edd.), they must be made up, With the use of the verb in Mt 108 may be compared Sy// 5031° where a certain man is extolled because, in addition to other benefactions, παρέσχεν ἰατ]ρὸν τὸν θεραπεύσοντία τοὺς ἀσθενοῦντας ἐν rile] παν[ηγύρει]. See also P Par 5! (8.6. 114) ἀσθενῶν τοῖς ὄμμασι (so also P Leid Mi), 26. 63'¥. 122 (B.c, 165) κατὰ τῶν ἀσθενούντων καὶ μὴ δυναμένων ὑπουργεῖν, BGU III. 84432 (A.D. 83) κόπους γάρ po[t] παρέχει ἀσθενοῦντει. In ἀσθένημα δῦ P Lond 144 (? i/A.p.) (=II. p. 253) a servant complains that he had been without food (ἀσειτήσαντος) for two days, as the boy who brought his provisions ‘‘ was sick,’’ ἀσθενήσαντος: cf. P Lond 22% (B.c. 164-3) (=I. p. 7) where ἀσθενῶς διακειμένας is used to describe the “sorry plight ἡ of the twins in the Serapeum owing to the withholding of their allowances of oil and bread. In Pro/eg. p. 11 the very vernacular letter BGU III. 948° (Christian, iv/v A.D.) is quoted for its closeness to Lk 1318: 4 μήτηρ cov K. acbevi, εἰδοῦ, δέκα tpis μῆνες. (See under ἰδού) ἬἩσθένηκα is answered by ἐὰν κομψῶς σχῶ in P Tebt II. 414° (ii/a.D.). The compound ἐξασθενέω is found in BGU III. 903% (ii/A.D.) as now amended, τοὺς πλείστους ἐξασθενήσαντας ἀνακεχωρηκέναι κτλ. : cf. also P Tebt I. 50% (Β. 6. 112-1), where for ἐξησθενηκώς the editors hesitate between the meanings ““ was impoverished ”’ or δ fell ill.’’ Add PSI τοι" (ii/A.D.) οὕσπερ ἐξασθενήσαντας ἀνακεχωρηκέναι : the last three substantial men of the village had emigrated because they could not stand the taxation.
