STRONGS NT 2978: λαῖλαψ

λαῖλαψ ((L T Tr WH) not λαῖλαψ (Griesbach), cf. Winers Grammar, § 6, 1 e.; Lipsius, Grammat. Untersuch., p. 37f; (Chandler § 620; Tdf. Proleg., p. 101)), λαίλαπος, ἡ (masculine in א* Mark 4:37; cf. Thomas Magister, Ritschl edition, p. 226, 4), a whirlwind, tempestuous wind: 2 Peter 2:17; λαῖλαψ ἀνέμου (cf. German Sturmwind; ἄνεμος σύν λαίλαπι πολλή, Homer, Iliad 17, 57), a violent attack of wind (A. V. a storm of wind), a squall ((see below)), Mark 4:37; Luke 8:23. (The Sept., Job 21:18; Job 38:1; Wis. 5:15, 24; Sir. 48:9.) (According to Schmidt (chapter 55 § 13), λαῖλαψ is never a single gust, nor a steadily blowing wind, however violent; but a storm breaking forth from black thunder-clouds in furious gusts, with floods of rain, and throwing everything topsy-turvy; according to Aristotle, de mund. 4, p. 395{a}, 7 it is 'a whirlwind revolving from below upward.')
