1. . < ἐπιοῦσα (sc. ἡμέρα) (or, < ἐπὶ τὴν ἰοῦσαν (sc. ήμέραν), Zorell, s.v.), hence, for the morrow or for the coming day (R, mg.).
(a) . < ἐπί + οὐσία, hence, for subsistence, needful (Am. R, mg.); (b) . < ἐπί + εἶναι in fem. ptcp. form, hence, pertaining to (the day). For renderings of versions and views of various writers, v. reff. in DB, ext., 36 f.; DCG, ii, 58 f., 62a; ICC on Lk, l.c. The EV, daily, is based on the Vg. (Lk; OL, Mt, Lk, quotidianus).
