Question: What is the significance of story of the Manna?
Answer: Many commentaries explain that the story of the Manna teaches us about the mechanics of earning a livelihood. Although we must put forth an effort to obtain an income, our livelihood is ultimately a gift from above – like the Manna. This being the case, a person should recognize that putting forth more effort than required will not yield more money.
To this extent we read in the Torah that those Jews who gathered more Manna than their family needed found their extra Manna spoiled in the morning.
It seems to me that the reason that G-d commanded Moses to place a portion of Manna in a flask that would remain in the ark forever, was that G-d desired that the Manna serve as an eternal sign that it is ultimately G-d who provides.
