Musar su Salmi 8:5

And this is the language of the holy Zohar in Parshath Terumah on Psalms 129:126): "It is a time to act for the L-rd," viz.: "So long as the Torah endures in the world and men occupy themselves with it, the Holy One Blessed be He rejoices in the work of His hands and rejoices in all of the worlds, and the heavens and the earth remain standing. What is more, the Holy One Blessed be He gathers all His tribunal and says to them: 'See the holy people that I have on the earth, by whom the Torah is adorned. See My handiwork, about which you have said: 'What is man that You remember him?'" And when they see the joy of their Master in His people, they immediately open [their mouths] and say (I Chronicles 17:21): 'Who is like Your people, Israel, one nation in the land?' But when Israel neglect Torah, His strength, as it were, weakens, wherefore "it is a time [for you] to act for the L-rd.' These are the tzaddikim who are left. They must gird their loins and perform good deeds, so that the Holy One Blessed be He will strengthen Himself to rejoice with the tzaddikim and with His camps and battalions. Why so? (Psalms, Ibid.): [For] 'they have violated Your Torah,' and the men of the world do not occupy themselves with it as is fitting."

The righteous spies that Joshua sent out repaired the metaphysical damage caused by ten of the original spies whom Moses had sent out. The "hope" for the future of the Jewish people was summarized by the תקות חוט השני, whereas the damage caused by the original spies can be described as symbolizing the statement of our sages that תקות אנוש רימה, that the only thing humans have to look forward to is to become worms (man's body in the grave). All this because they abused their power of speech to libel G–d and the land of Israel. At the root of their corruption lay their desire to occupy positions of influence within the nation. All that the above teaches is to follow very carefully the advice of our sages in Avot 4,4, "be very very humble, seeing that man's prospects are only to decay!" The spies who had started out by being described as אנשים, i.e. men of stature, ended up by being considered "אנוש," the lowest appellation of humans.
