נוּם
to slumber (from drowsiness)
Definition
The Hebrew verb נוּם (nûwm) means to slumber, doze, or sleep lightly, often implying a state of drowsiness rather than deep sleep. It describes a temporary lapse in alertness or vigilance, as seen in Psalm 121:3-4, where it emphasizes God's unwavering watchfulness over His people. In some contexts, it conveys negligence or spiritual dullness, such as the watchmen who are blind and 'slumbering' in Isaiah 56:10. The word can also depict a sudden, divinely imposed stupor, as when God strikes the mighty warriors so they 'sleep' in Psalm 76:5.
Biblical Usage
נוּם appears six times in the Old Testament, primarily in poetic and prophetic books. It is used positively to contrast human frailty with God's eternal vigilance in Psalms 121:3-4. Negatively, it describes the spiritual lethargy of Israel's leaders in Isaiah 56:10 and the complacency of Nineveh's defenders in Nahum 3:18. In Isaiah 5:27, it highlights the relentless readiness of God's instruments of judgment, who do not slumber. The word consistently portrays a lapse in wakefulness, whether physical, moral, or spiritual.
Etymology
נוּם is a primitive root in Hebrew, meaning it is not derived from another Hebrew word. It is related to the concept of nodding off or drowsing. Cognates appear in other Semitic languages, such as Arabic (nāma, 'to sleep') and Aramaic, suggesting an ancient root for light sleep. The meaning developed to include metaphorical senses of negligence or inattention in biblical usage.
Semantic Range
This word is theologically significant as it contrasts human weakness with divine sovereignty. In Psalms 121:3-4, God's refusal to slumber underscores His constant protection and covenantal faithfulness, a key doctrine of providence. Conversely, human slumber in Isaiah 56:10 and Nahum 3:18 illustrates spiritual apathy and judgment, warning believers against complacency. Understanding נוּ姆 enriches reading by highlighting the biblical call to vigilance (e.g., 1 Thessalonians 5:6) and reliance on God's unwavering watchfulness.
In ancient Near Eastern culture, watchmen were essential for city security, making their slumber a grave failure with life-or-death consequences, as reflected in Isaiah 56:10. Light sleep was also associated with vulnerability, contrasting with the deep trust in God's protection. The cultural understanding of slumber as a sign of negligence or divine intervention (as in Psalm 76:5) differs from modern views of sleep as merely physiological.
ישׁן (yāshēn, H3462) — denotes deep, ordinary sleep; שׁכב (shākav, H7901) — means to lie down, often for rest or sleep; תּרדּמה (tardēmâ, H8639) — refers to a deep, divinely induced sleep or trance, as in Genesis 2:21.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
