Word Study

In depth

A plain-language study of nystázō — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word nystázō, represented by G3573, means to slumber. Its definition is to nod, i.e. (by implication) to fall asleep, or figuratively, to delay. It appears 2 times across 2 unique verses in the Bible, capturing a state of drowsiness that can represent either physical sleep or a figurative lack of activity.

Biblical Occurrences & Contextual Analysis

In the biblical narrative, G3573 is used in two key ways. In a literal sense, it describes the physical state of the ten virgins in the parable, who slumbered and slept while the bridegroom tarried Matthew 25:5. Figuratively, it is used to emphasize the certainty of divine justice, stating that the damnation of false teachers slumbereth not, meaning their punishment is neither inactive nor delayed 2 Peter 2:3.

Related Words & Concepts

Several related words help clarify the concept of slumber and wakefulness:

  • G2518 katheúdō (to lie down to rest, i.e. (by implication) to fall asleep (literally or figuratively)): Used directly with nystázō in Matthew 25:5, this term often warns against spiritual lethargy, urging believers not to sleep as others do, but to remain watchful 1 Thessalonians 5:6.
  • G5549 chronízō (to take time, i.e. linger): This word explains the reason for the slumber in Matthew 25:5, as the bridegroom tarried. It points to a period of waiting or perceived delay that can test a person's preparedness.
  • G684 apṓleia (ruin or loss (physical, spiritual or eternal)): This is what does not slumber. The term refers to damnation or perdition, the certain end for those who follow the path to destruction Matthew 7:13 and for the "son of perdition" 2 Thessalonians 2:3.

Theological Significance

The theological weight of G3573 is found in its contrasting applications.

  • Warning Against Spiritual Lethargy: To slumber in the context of waiting for the bridegroom is a warning against spiritual unpreparedness. It illustrates how a period of delay can lead to a lack of readiness for Christ's return Matthew 25:5.
  • The Certainty of Judgment: The declaration that damnation "slumbereth not" is a powerful assurance of God's active justice. It communicates that for those who use "feigned words" to exploit others, judgment is not a distant or inactive threat but an impending and inescapable reality 2 Peter 2:3.
  • Human Weakness vs. Divine Action: The uses of G3573 highlight a stark contrast. Humans may slumber and grow weary while waiting for the Lord, but God's judgment never sleeps or delays. This underscores the difference between human fallibility and divine certainty.

Summary

In summary, G3573 is more than just a word for nodding off. It serves as both a literal illustration of the need for spiritual vigilance and a figurative guarantee of God's unceasing justice. The term powerfully contrasts the human tendency to become drowsy while waiting with the absolute certainty of a judgment that is always awake and active.
