Topical Lexicon
Semantic Range and Imagery

כָּשָׂה in its lone biblical appearance (Deuteronomy 32:15) conveys the idea of becoming “sleek,” “polished,” or “glossy with fat.” It pictures an animal whose coat shines because it has been over-fed. The verb therefore operates as an image of overabundance that produces outward smoothness but inward softness—prosperity that dulls spiritual alertness.

Literary Context within Deuteronomy

Moses’ “Song” (Deuteronomy 32:1-43) rehearses the LORD’s faithfulness contrasted with Israel’s future unfaithfulness. The three-part description—“fat, sleek, and corpulent” (Deuteronomy 32:15)—places כָּשָׂה between two synonyms for obesity. The middle verb intensifies the progression from simple weight gain (“fat”) to conspicuous, self-indulgent luxuriance (“sleek”), ending in heavy sluggishness (“corpulent”). Moses warns that Israel’s covenant infidelity will not spring from want but from satiety.

Historical Background

Ancient Near-Eastern agrarian life treated fatness as a sign of blessing (cf. Genesis 45:18; Proverbs 13:4). Yet the covenant law had already warned that such blessing could provoke forgetfulness (Deuteronomy 8:10-14). The Song prophetic­ly sets Israel’s later history in miniature: national expansion under David-Solomon, followed by complacency, idolatry, and eventual exile (2 Kings 17:7-23; 2 Chronicles 36:14-21).

Theological Themes

1. Blessing as a Test: Material prosperity exposes the heart (Deuteronomy 8:2).
2. Ingratitude and Apostasy: “He abandoned the God who made him and scorned the Rock of his salvation” (Deuteronomy 32:15). Abundance, when isolated from covenant remembrance, degenerates into contempt.
3. Divine Retribution and Mercy: The same chapter balances judgment (32:23-25) with ultimate compassion (32:36-43), showing that God disciplines in order to restore.

Intercanonical Parallels

• “They were filled, and their hearts became proud; therefore they forgot Me” (Hosea 13:6).
• “Lest I be full and deny You and say, ‘Who is the LORD?’” (Proverbs 30:9).
• “You say, ‘I am rich…’ not realizing that you are wretched and pitiable” (Revelation 3:17).

These texts echo the כָּשָׂה warning: comfort can smother dependence on God.

Ministry and Pastoral Implications

• Discipleship must address the spiritual hazards of comfort as seriously as the trials of hardship.
• Corporate worship should regularly recount salvation history so that blessing is tied to gratitude.
• Stewardship teaching ought to turn prosperity into generosity (2 Corinthians 9:8-11), preventing the “sleek” heart from calcifying.
• Leaders should monitor signs of spiritual lethargy—prayerlessness, decreased hunger for Scripture, neglect of mission—within prosperous congregations.

Homiletical Outline Suggestion

1. Prosperity Received (God’s gracious provision).
2. Prosperity Misused (כָּשָׂה—sleek complacency).
3. Prosperity Reclaimed (repentance and renewed dependence).

Summary

כָּשָׂה captures the peril of prosperity: when blessing polishes the exterior, the heart may grow dull to its Redeemer. Deuteronomy 32:15 stands as a perpetual sentinel, calling God’s people to gratefully steward abundance rather than let abundance master them.
