Topical Lexicon
Word Usage and Narrative Settings

The term appears ten times, moving through a remarkable sweep of settings—battlefields (Judges), prophetic poetry (Isaiah, Habakkuk), denunciations of idolatry and imperial hubris (Isaiah, Jeremiah), personal prophetic prayer (Daniel), and earthy moral exhortation (Jeremiah). In each setting it marks a boundary: where human strength ends and either divine help or divine judgment begins.

Physical Weariness in Battle and Labor

Judges 8:15 portrays Gideon’s three hundred as “exhausted,” yet still pursuing the Midianite kings. The word highlights both their vulnerability and the faith-driven perseverance that secured victory.
Isaiah 44:12 pictures the idol-smith who “grows faint” at his forge, a poignant contrast: the craftsman tires, while the lifeless idol he shapes can never supply strength.
Jeremiah 51:58 and 51:64, together with Habakkuk 2:13, pronounce that the peoples “exhaust themselves for nothing.” Colossal walls, flaming gates, and frantic building projects cannot outlast the decree of the Lord of Hosts. Here the word becomes an indictment of self-reliance and the futile expenditure of nations that ignore God.

Spiritual Fatigue and Divine Renewal

Nowhere is the contrast sharper than in Isaiah 40.

“Even youths grow tired and weary, and young men stumble and fall, but those who wait upon the LORD will renew their strength” (Isaiah 40:30-31). The Creator “will not grow tired or weary” (verse 28), so the exhausted find hope—not in themselves, but in Him who is tireless. The term thus serves the prophet’s call to faith: human frailty met by divine sufficiency.

Untamed Desire and Moral Weariness

Jeremiah 2:24 uses the word negatively: pursuers of a wild donkey “need not weary themselves” because its unbridled passion makes capture easy. The verse turns physical exhaustion into a moral lesson—unchecked desire wears out the seeker as surely as idolatry drains a nation.

God’s Messenger and Supernatural Swiftness

A striking nuance surfaces in Daniel 9:21. Gabriel comes “in swift flight,” the same root that elsewhere signals fatigue. The juxtaposition is intentional: while mortals falter, the ministering spirit moves with unhindered rapidity at God’s command. What exhausts humanity is effortless for the heavenly envoy.

Ministry Themes and Pastoral Application

1. Human limitation is universal—warriors, craftsmen, nations, and even youth succumb.
2. God’s inexhaustible power is equally universal, offered to the covenant people who “wait upon the LORD.”
3. Idolatry and self-made empires promise strength but deliver depletion.
4. Divine purpose prevails speedily; heaven’s servants are never hindered by the weariness that besets earth.

For preaching and discipleship the passages invite believers to exchange striving for trusting, to labor in the Lord rather than in vain, and to remember that the God who sends Gabriel swiftly is the same who renews strength for those who hope in Him.
