Musar su II Samuele 22:9

We have learned in Avot 4,21, that "jealousy, lust, greed, and ego (i.e. the desire for public recognition) drive man from this world." These very negative virtues had driven Adam from the world. There was the jealousy of the serpent of Adam possessing Eve, its pursuit to gratify its lust, and the pursuit of ego, i.e. Adam and Eve wanted to usurp the unique place of G–d in the universe, since they responded to the lure והייתם כאלוקים, "you will be like G–d." Eve had squeezed out a cluster of grapes, ate it, found that they were unripe. This suggests that in this material world one must not pursue honor. Honor will be inherited by the scholars in the world to come. At that time what is written in Isaiah 24,23: "G–d's Presence will be revealed to His elders," will be fulfilled. This is what is meant when the sages describe יין המשומר, "well aged wine," as being part of the reward in store for the righteous in the future. Concerning what happens to the wicked at that time, it is written in Malachi 3,19: "For lo! that day is at hand, burning like a furnace.. All the arrogant and doers of evil shall be straw, etc." It also says in Samuel II 22,9: "smoke rose from His nostrils," i.e. when G–d was angry, and burned those whom He was angry at." Since we have shown that what happens on earth has its counterpart in the heavens, the Torah reports that the season the spies were dispatched was when the grape harvest commences on earth, i.e. a hint that many grapes are not ripe yet. The spies ignored the items mentioned in Avot as destructive. They ate unripe grapes, i.e they were greedy, they were concerned with their own honor and glory, hence they had to suffer what is described in Proverbs 10,26.
