The spies’ heightened but misdirected spiritual orientation led them astray. The spies wanted to experience life and pursue G‑dliness unencumbered by the distractions of materiality. In the desert, the Jewish people were protected by the Clouds of Glory, sustained by the manna and the well of Miriam, and all their physical needs were fully attended to. All of their time was spent in the study of the Torah, in meditation, and in prayer. The spies were repulsed by the notion of entering the real world, where we must waste time working for our daily bread. The vision of a life devoted to expanding our Divine consciousness unburdened by material distractions is of course praiseworthy. This vision has inspired us to yearn throughout history for the Messianic era, when the materiality of the world will no longer distort our spiritual focus.
Nonetheless, this yearning must be balanced with humble submission to G‑d’s plan. The purpose of life is to live within mundane reality, revealing the G‑dliness concealed within it. Only by entering the material world can G‑d’s essence be found, through fulfilling His commandments on the physical plane.1


This is a Jewish reading we do to our ancestors, always trying to make up for their mistakes with something that looks good.
Fact is: the whole point HaShem had of taking the people out of Egypt was to have them in their Canaan Promise Land, with honey and milk.
Those spies weren't holy folks thinking about studying in the desert rather than fighting for their promise land.
They were unfaithful, completely ignoring HaShem's power and miracles previously done.
HaShem had mercy on them on the Gold Calf sin, but not this time, condemning them to die without seeing the promise fulfilled.
This is proved by Caleb and Joshua! And they lived to see the promise fulfilled still studying the Torah and writing the Mishna.
I pray for our Judaism and our attempt to justify sins of our people won't overshadow the truth in the Torah. As the prophet Jeremiah said, we'd be call light darkness and darkness light. Truth a lie and lies, the truth, G-d forbid.
