The men selected to scout out the land of Israel were no ordinary men. They were chosen because they held stature among the nation – they were great people, yet they gravely erred. One of the reasons Chazal understand to have motivated their plot was that life in the desert was simple and beautiful. God did everything for them, and the people were exposed at all times to the Almighty.
They had the manna to eat, which would be sent based on worthiness and potentially taste of anything they desired. They had a wellspring that moved with the camp. They had Clouds of Glory which marked travel movements and shaded them from the harsh desert sun; and according to Midrash, flattened obstacles, cleared wild beasts, and possibly cleaned their clothing too.
The spies concluded that this was an ideal way of life and engineered a report that would get the people to clamour to stay in the wilderness.
The Sfas Emes notes that immediately afterward the story of the spies concludes, three mitzvos are revealed: separating challa, Tzitzis, and nesachim – wherein all sacrifices require additions from the mineral water 0, among them salt and spring water.
The Sfas Emes notes that the sin of the spies was that they presumed to instruct God how things ought to be. These specific mitzvos show the flaw in their argument. God did not want us to live in the desert indefinitely, eating miraculous manna, drinking from the miraculous well, under the miraculous Clouds – the training wheels have to come off eventually.
What man is independently capable of is elevating the mundane and material into spiritual . These mitzvos capture the concept.
The manna was the bread that God sent to their doorsteps. The mitzva of challa requires that when baking a loaf of bread, a small section is set aside to remind that God is the true provider. The entire loaf is called “challa”, although the mitzva only pertains to the small bit set aside. The bread that has been planted, grown, cultivated and processed becomes more.
The Clouds surrounded sheltered them and reminded them of God’s immanence and presence. Similarly, tzitzis ensconce and shroud a person – the stated aim is to remind the wearer of all mitzvos. Physical shelter and protection become more.
The wellspring that followed them around was how they drank. Similarly, the nesachim of minerals and spring water accompanied every sacrifice. The literal translation of Korban is to draw close – things mundane as minerals become more.
God does not want to give things to us for free, as this makes them cheap. The spies presumed to know that a life devoid of physicality was perfect, but these mitzvos serve indicate otherwise.
Mankind has the potential to elevate everything into something spiritual – with just a little direction.
