νήφω

nḗphō

G3525 verb

SILEX Entry

Definition

To be sober, to be free from the effects of intoxicants; by extension, to be self-controlled, well-balanced, vigilant, and clear-headed. The core meaning involves literal sobriety (not under the influence of wine or strong drink), but it frequently acquires a figurative sense: being mentally and spiritually alert or vigilant, exercising restraint and sound judgment.

Semantic Range

to abstain from wine, to be physically sober, to be alert, to exercise self-restraint, to be watchful, to maintain moral or spiritual clarity

Root / Etymology

The precise etymology is uncertain; likely related to a stem associated with sobriety or wakefulness, but no direct cognate is attested in classical Greek. Some lexicographers suggest a relationship to the negative prefix νη- and a root related to drinking or inebriation (but no exact stem), but this is speculative.

Historical & Contextual Notes

In classical Greek, νήφω is quite rare; its use is virtually absent in the major classical authors. In the Hellenistic and Koine periods, especially in the New Testament (e.g., 1 Thessalonians 5:6, 8; 1 Peter 1:13, 4:7, 5:8), it assumes a spiritual and moral dimension, emphasizing clarity of mind, alertness, and self-mastery, sometimes in contrast to intoxication but often in the context of vigilance against moral or spiritual dangers. In the Septuagint, it is very infrequently used. The extended sense of mental and moral alertness distinguishes it from related terms that focus only on physical drunkenness or temperance. Many standard English translations render νήφω as "be sober" or "be self-controlled," but these sometimes miss the full nuance of "wakeful alertness" and "vigilant clarity" implied in moral or spiritual situations. The term stands in contrast to μέθω (to be drunk) and is often paired with ἐγρηγορέω (to be watchful).

νήφω in the NT most naturally and commonly carries the sense “be sober” — literally not intoxicated and figuratively alert, self-controlled, and vigilant. ‘Be sober’ preserves the stative/continuing quality of the Greek, covers both literal and figurative uses, and matches typical, natural English translation practice.
