ἀγρυπνέω, -ῶ (ἄγρυπνος,
seeking sleep; ἀγρεύω, ὕπνος), [in LXX chiefly for שׁקד;]
to be sleepless, wakeful (Theogn, Xen, al.); metaphorically (LXX) = cl. ἐγρήγορα,
to be watchful, vigilant: Mrk.13:33, Luk.21:36, Eph.6:18, Heb.13:17.
SYN.: γρηγορέω, which see; νήφω, associated with γ. in 1Pe.5:8, expressing a wariness which results from self-control, a condition of moral, not merely mental alertness (see M,
Th., I, 5:6). (
