G1893 — ἐπεί

(from temporal ἐπί and εἰ, literally, thereupon when; Curtius, Erläut. etc., p. 182; cf. Etym. Magn. 356, 7), conjunction (Latincum), when, since (cf. Winer's Grammar, § 53, 1); used:

1. of time, after; so once in the N. T.: Luk 7:1 (where L T Tr text WH text ἐπειδή).

2. of cause, etc., since, seeing that, because: Mat 18:32; (Mat 21:40 T Tr WH); ; Mar 15:42; Luk 1:34; Joh 13:29; Joh 19:31; 1Co 14:12; 2Co 11:18; 2Co 13:3; Heb 5:2, Heb 5:11; Heb 6:13; Heb 9:17; Heb 11:11; ἐπεί οὖν since then, Heb 2:14; Heb 4:6. Agreeably to a very common abbreviation of speech, we must often supply in thought between ἐπεί and the proposition depending upon it some such phrase as if it is (or were) otherwise; so that the particle, although retaining the force of since, is yet to be rendered otherwise, else, or for then (German sonst); so in Rom 11:6, Rom 11:22; Heb 9:26; ἐπεί ἄρα, 1Co 5:10; 1Co 7:14 (cf. Winer's Grammar, § 53, 8 a.); ἐπεί alone before a question (cf. Winers Grammar, 480 (417); Buttmann, 233 (200)): Rom 3:6; 1Co 14:16; 1Co 15:29; Heb 10:2; (4 Macc. 1:33; 2:7, 19; 6:34 (4 Macc 6:35>); 4 Maccabees 7:21; 8:8>). Cf.
