The tragic fall of a nation is rarely just a matter of inferior military might; it is almost always the final symptom of a deep internal collapse. The Israelites' defeat by their enemies was not due to the overwhelming strength of the attackers, but was a direct consequence of their own spiritual decay [מצודת דוד]. They broke their foundational covenant, which was the Torah itself, given to them as a binding agreement [מצודת דוד].
To understand how such a profound spiritual failure occurred, one must look at the inseparable link between studying the Torah and actually observing its Commandments. When the Israelites originally stood at Mount Sinai and accepted the Torah, they were completely free from any evil impulses. In that pure state, they were able to fulfill the will of God naturally and out of pure love. However, this condition was lost following the sin of the Golden Calf, which allowed the evil impulse to return and take root within the people [חומת אנך].
Once human nature was compromised, the only way to overcome these inner urges and properly observe the Commandments was through dedicated Torah study. This active study acts as an essential antidote that neutralizes the evil impulse. Therefore, the nation's failure to listen to God was not merely a general refusal to obey. It was, first and foremost, a complete abandonment of Torah study. Without this vital defense, their destructive urges naturally grew stronger, inevitably leading the people to violate their covenant [חומת אנך].
This breach of the covenant manifested in idolatry and other severe transgressions. Committing these sins is considered equivalent to completely rejecting the Torah and everything Moses was commanded to teach. The entire tragic sequence follows a clear path of cause and effect: because the people stopped listening and studying, they lost their ability to control their impulses, which ultimately guaranteed they would fail to live properly and perform the required actions [חומת אנך].
