The Sin of the Spies and the Tree of Knowledge: A Surprising Connection

This week's Torah portion, Parashat Devarim, presents Moshe Rabbeinu's powerful farewell address to the Jewish people. It is always read on Shabbat Chazon, the Shabbat before Tisha B'Av.

Standing just before his passing, Moshe chooses to revisit some of the nation's deepest failures. He reminds the people of the sin of the spies, the night of weeping that Chazal identify as the origin of Tisha B'Av, and recalls the moments when the Jewish people fell short of their Divine mission.

Moshe also reminds them of the consequence of that sin. The generation that refused to enter the Land of Israel would never merit to do so. Only their children would inherit the land.

When referring to those children, Moshe uses a striking expression: "...and your children, who today do not know good and evil, they shall enter there; to them I will give it, and they shall possess it" (Deuteronomy 1:39).

On the simple level, Moshe is referring to those who were too young at the time of the sin of the spies to distinguish between good and evil, and therefore were not held accountable for the nation's actions (see Ibn Ezra).

Yet the phrase "know good and evil" immediately brings to mind the Tree of the Knowledge of Good and Evil in Gan Eden. Is Moshe intentionally drawing a connection between these two events? And if so, what does the sin of the spies have to do with the Tree of Knowledge? More importantly, what does this teach us today, as we approach Tisha B'Av and mourn the destruction of the Beit Hamikdash and the exile of the Jewish people?

The Striking Similarities

There are several remarkable parallels between the two stories.

When Moshe sends the spies into the land, he instructs them to determine whether "there is a tree in it or not" (Numbers 13:20). Beyond the verse's simple meaning (see Rashi), the mention of a tree naturally recalls the Tree of Knowledge in Gan Eden.

Moshe also tells the spies, "Be strong and take of the fruit of the land." In Gan Eden, Adam and Chava were commanded not to eat the fruit of the forbidden tree. Here, the spies are commanded to strengthen themselves and take from the fruit of the land. The wording itself is revealing. In Gan Eden, strength was needed to resist eating. Here, strength was needed to overcome hesitation and eat.

The consequences of the two sins are also remarkably similar. After the sin of the spies, the generation is sentenced to die in the wilderness and is denied entry into the Land of Israel. After the sin of the Tree of Knowledge, Adam and Chava are sentenced to death and expelled from Gan Eden. Both stories end with death and exile from a place of blessing.

Another fascinating parallel lies in the debate itself. The forbidden tree is called the Tree of the Knowledge of Good and Evil, while the spies are specifically instructed to determine whether the land is "good or bad" (Numbers 13:19). The entire dispute revolves around that question. The spies conclude that Egypt would have been preferable, while Yehoshua and Kalev proclaim that "the land is very, very good." In both stories, the central issue is determining what is truly good and what is truly bad.

Who Decides What Is Good?

The connection between these two episodes appears to be fundamental.

The central lesson of the Tree of Knowledge is that human beings are not capable of independently defining good and evil. Only Hashem possesses absolute knowledge of what is truly good and what is truly bad.

Throughout Bereishit, the Torah repeatedly states, "Hashem saw that it was good." Likewise, the prophet Isaiah declares, "I form light and create darkness, make peace and create evil; I am Hashem, Who does all these things" (Isaiah 45:7).

Human beings are naturally subjective. We tend to define good according to what feels pleasant or beneficial at the moment. Hashem, however, sees the complete picture.

By placing one tree off limits, Hashem established a fundamental principle: He alone determines what is good and what is bad. Adam and Chava rejected that principle when Chava "saw that the tree was good for food." It appeared good in her eyes, and that became the root of the sin.

The spies repeated the same mistake. Hashem had already described the Land of Israel as "a good and spacious land, a land flowing with milk and honey" (Exodus 3:8). Yet the spies reached their own conclusion. They judged the land according to their own understanding rather than trusting Hashem's definition. In doing so, they repeated the mistake of Adam and Chava.

It is therefore fitting that the generation denied entry into the land was replaced by children "who did not know good and evil"—those who had not yet placed their own judgment above Hashem's.

The Meaning of Faith

Perhaps the spies' mistake was not the facts they reported. It is entirely possible that their description of the land and its inhabitants was accurate. Their real failure came in the conclusion they drew. They decided that the land could not be conquered, despite Hashem's promise.

Instead, they could have said, "Master of the Universe, You told us this land is good. It looks frightening to us, and we are afraid, but we trust that Your promise is true."

Faith does not require denying reality. It means trusting Hashem even when reality seems to point in the opposite direction.

This is precisely Moshe's rebuke in our parsha: "Yet in this matter, you do not believe in Hashem your God" (Deuteronomy 1:32).

The Jewish people had witnessed the Ten Plagues, the splitting of the Red Sea, and countless miracles. Clearly, Moshe was not saying they doubted Hashem's existence.

Rather, emunah in the Torah means steadfast trust.

The first appearance of the word emunah is during the battle with Amalek, when Moshe's hands remained steady until sunset (Exodus 17:12). Ramban and Rashbam explain that the word conveys firmness, strength, and unwavering persistence.

That is the lesson Moshe wanted the people to learn. Faith is not merely believing that Hashem exists. It is continuing to rely on Him when circumstances appear frightening and His promises seem difficult to understand.

The Message Before Tisha B'Av

As Tisha B'Av approaches, Moshe's message speaks directly to every generation.

The repair for the sin of the spies is not simply strengthening our belief that Hashem exists. It is strengthening our trust in Him, especially when His plan is difficult to understand.

Real faith begins where human certainty ends.
