verb | aor.subj. ἐκλίπω | λείπω
57.46 · Possess, Transfer, Exchange · Need, Lack
to give out, to fail to change to a state in which something is lacking or insufficient ‘To give out’ may be expressed as ‘to no longer exist’ or ‘no longer to have any.’
15.58 · Linear Movement · Leave, Depart, Flee, Escape, Send
to depart out of, to leave from to depart out of a place This meaning is only found as a variant reading: κἀκείνους κατέ λειπεν ἐκεῖ καὶ ἔκλειπεν ‘he left them behind there and departed’ ACT 18:19 (apparatus).
68.36 · Aspect · Cease, Stop
to cease, to stop, to forsake to cease from an activity which has gone on for some time In this phrase in LUK 23:45 there is an evident ellipsis of an expression meaning ‘to shine.’
13.39 · Be, Become, Exist, Happen · State
to cease, to die out, to come to an end to cease, of a state, with the implication of nothing of the state continuing to exist
1 It would be possible to interpret ἐκλείπω[a] as a change in a state of existence, and hence it could be treated as a negation of existence (Domain 13), but one could also analyze the meaning of ἐκλείπω[a] as a negation of quantity and thus treat it in Domain 59.

Moulton & Milligan — Vocabulary of the Greek NT
ἐκλείπω. Notwithstanding Field (Λοίες, p. 79) and Moffatt, it seems more than doubtful that in Lk 2315 any reference is intended to an eclipse. To find such a reference is to involve the Evangelist in a needless blunder, as an ec/zfse is impossible at full moon, and to run counter to his general usage of the verb = ‘‘fail”’ (16°, 2255, cp. Heb 112). For this meaning cf. P Hamb I. 2714 (B.C. 250) ἐάν τι αὐτῶν ἐγλιμπάνηι, P Leid Bii-7 (B.c. 164) els τὸ μηθὲν ἡμᾶς τῶν δεόντων ἐγλιπεῖν, and even 76. Wi*-6(ii/iii A.D.) τὴν ὥραν ἐν ἡ μέλλι (1. μέλλει) ἡ σελήνη ἐκλίπειν (1. ἐκλείπειν), ‘“horam in qua luna deficiet (in ariete).”” Ρ Par 27}5 (8.6. 160) ἡμεῖς δὲ ἐν τῷ μεταξὺ διαλυόμεναι τῷ λιμῷ κινδυνεύομεν τὸ ἱερὸν ἐγλείπειν ᾽ ’ €KAEKTOS shows ἐ. followed by the acc. of place. In P Tebt I. 105** (B.c. 103) and 106*8 (B.C. 101) it is used of ‘‘ renouncing ”’ a lease—éyAureitv τὴν μίσθωσιν : for a similar use of the subst. cf. P Lond 1166® (a.p. 42) (=TIII. p. 104) pexpt ἐκλείψεως τῶν λονομένω(ν). From the inscrr. may be cited Syl 2261 (iii/B.c.) ἐγλείπειν τὴν πόλιν, and OG/S gol® (the Rosetta stone—B.C. 196) τά Te ἐγλελειμμένα πάντα ἐν τοῖς πρότερον χρόνοις ἀποκατέστησεν els τὴν καθήκουσαν τάξιν. On the form ἐγλείπειν see Mayser Gr. p. 227.
