T.: οὐκ ἀδυνατήσει παρά τῷ Θεῷ (τοῦ Θεοῦ L marginal reading T Tr WH) πᾶν ῤῆμα, Luk_1:37 (the Sept. Gen_18:14) (others retain the active sense here: from God no word shall be without power, see παρά, I. b. cf.

ἀδυνατέω [page 10] Applied to persons this verb retains its classic sense, to be incapable, in late Greek : cf. P Par 35 .36 (B.C. 163), διὰ τὸ ἐμὲ ἐν κατοχεῖ ὄντα ἀδυνατεῖν , ib. 63 .13 f. (B.C. 165) ὅπως μήτεν τῶν ἀδυνατούντων γεωργεῖν περισπᾶται μηθείς , and .89 f. τοὺς ἀδυνατοῦντας ἀναγκάζειν ἐπιδέχεσθαι τὰ τῆς γεωργίας . The neuter sense, to be impossible, when applied to things, appears in the LXX, which seems to tell in favour of the AV rendering in Luk_1:37 , as against the RV : see Hatch Essays p. 4, Field Notes p. 46 f., where the true reading παρὰ τοῦ θεοῦ (RV) is rendered for from God no word (or, nothing) shall be impossible.
