A nation's accumulation of immense wealth and military power often appears as the ultimate symbol of success. Yet, this very abundance can serve as the catalyst for profound spiritual collapse and the embrace of foreign influences. The relentless pursuit of riches and military might was driven by a deep-seated desire to imitate neighboring nations and adopt their customs. This ambition directly violated the Torah's commandments, which placed specific limits on the wealth and military buildup of an Israelite king [שד״ל]. The sheer scale of this material and military prosperity highlights the severity of the people's transgressions, identifying the central cause of their moral decay [מלבי״ם, מצודת דוד].
The roots of this decline trace back to the era of King Solomon. During his reign, gold was amassed from distant lands, silver became as common as ordinary stones, and horses were imported in staggering numbers [רד״ק, ביאור שטיינזלץ]. The intense focus on financial trade and the breeding of horses transformed into an endless, all-consuming goal [ביאור שטיינזלץ]. The obsession with military expansion even drove the people to return to Egypt for the sole purpose of acquiring more horses [מלבי״ם]. Although the accounts speak of limitless treasures and chariots [רש״י, מצודת ציון], this is an exaggeration meant to emphasize their massive volume [רד״ק]. Furthermore, silver is noted before gold simply because it was far more abundant [אבן עזרא].
Ultimately, this extreme material satisfaction and wealth caused the people to rebel against God and turn toward idolatry [רד״ק]. There is a striking progression in the nation's downfall. While earlier failures stemmed from relying on human wisdom, the focus here shifts to their pride in wealth and military strength. This dangerous combination mirrors the warning of the prophet Jeremiah, who cautioned against taking pride in one's wisdom, might, or riches [אבן עזרא].
