Moulton & Milligan — Vocabulary of the Greek NT
κλύδων [page 349]
Hort (on Jas_1:6 ) has pointed out that the proper sense of κλύδων is always rough water rather than wave : cf. Luk_8:24 , 1Ma_6:11 , and to the passages from profane sources cited by Armitage Robinson on Eph_4:14 add M. Anton. xii. 14 . The plur. = waves is found in Vett. Val. p. 344 .15 with reference to a ship exposed τοῖς . . μυρίοις κλύδωσιν .
