(ὁρμάω), [in LXX: Ho 5:10, Am 1:11 (עֶבְרָה), etc.;]
a rush: Re 18:21.†
Moulton & Milligan — Vocabulary of the Greek NT
ὅρμημα. The meaning of this NT ἅπ. εἰρ. in Rev 1821 is doubtful. It is often rendered ‘‘a rush,’’ ‘‘a mighty onset,” as in Deut 284°, but Charles (JCC ad 1. =II. p. 107 f.) suggests that the meaning is rather ‘‘indignation,” as in Hos 519 a/. See s.v. ὁρμή ad fin.
Liddell-Scott-Jones — Greek-English Lexicon
ὅρμημα (hormēma) — sudden violence. ὅρμ-ημα, ατος, τό, sudden rush, swoop, onset, ἀετοῦ [LXX]; of attacking troops,[LXX]; of the fall of a stone, [NT]: plural, rapid movement, ὁρμήμασι νηός, ={νηῒ ὁρμωμένη}, Oracle texts cited in [Refs 2nd c.AD+]
2. ={ὁρμή}, impulse, incitement, motive, μηδ᾽.. ἡμῶν τι συνεργὸν μηδ᾽ ὅ. [Refs 4th c.BC+]; τὸ ὅ. μου my indignation, [LXX]; θαλάσσης -ήματα, of the tides, [Refs 5th c.AD+]
II. the earliest exception is Ἑλένης ὁρμήματά τε στοναχάς τε [Refs 8th c.BC+] as the objective genitive, the cares (as if from ὁρμαίνω) and groans [of the Greeks] about Helen, i. e. caused by her; by the χωρίζοντες [Refs]searchings of heart and groans of Helen; the former view is more probably, but ὁ. may be from ὁρμάομαι and mean the rushes, struggles of war.
