תהלים, פרק צ״ה, פסוק י׳

The complex relationship between God and the Israelites who left Egypt eventually reached a breaking point, forever shaping their destiny in the desert. Following the sin of the spies, an entire generation faced a forty-year period of wandering marked by deep tension and divine judgment [רד״ק, ביאור שטיינזלץ].

The primary approach among commentators understands this period as one of continuous struggle and quarreling. For four decades, God engaged in an ongoing conflict with the people, culminating in the decree that they would die in the wilderness rather than enter the land [רש״י, רד״ק, מצודת ציון, מלבי״ם]. Other scholars view this era through a lens of profound rejection and disgust toward the entire generation [אבן עזרא, ביאור שטיינזלץ]. Highlighting the severity of this distance, [אבן עזרא] notes that Moses ceased to receive prophecy during these forty years.

Yet, alongside this intense anger and harsh punishment, there was also hidden mercy. Although the Israelites were sentenced to wander for one year for every day the spies had scouted the land, God shortened their actual travel days to ease their burden. Furthermore, during those forty years, no one died before reaching the age of sixty [חומת אנך]. Interestingly, this forty-year timeline also serves as a hint for the future, with some traditions suggesting that the Messianic era will similarly last forty years [תורה תמימה].

The root cause of this divine anger was the people's inner state. They wandered away from the straight path, much like a lost sheep [מצודת ציון]. Their hearts were simply not in the right place [ביאור שטיינזלץ]. Lacking true knowledge and faith, they turned toward evil [רד״ק, מאירי], allowing their evil inclination to rule over them and lead them astray [אלשיך].

The profound tragedy of this generation was their failure to recognize God's ways. Despite witnessing extraordinary miracles, they failed to internalize them. They succumbed to fear about entering the land, doubted their faith, and did not even realize that their inability to enter the land was a direct punishment from God [רד״ק, מאירי]. Even after forty years of rebuke and struggle, they still had not learned to truly understand His ways [מצודת דוד].

However, this lack of understanding is also viewed in a slightly different light. Relying on the principle that a person can only fully grasp the depth of their teacher's wisdom after forty years, some commentators suggest that this extended period was a necessary stage of spiritual development [אלשיך, אבן עזרא, מלבי״ם]. Only at the very end of their forty years of wandering could Moses tell the Israelites that God had not previously given them the heart to know. Only then, with the passage of time and the completion of their journey, were they finally capable of beginning to understand God's ways.
