Midrash sobre Ezequiel 34:25

Rabbi Phineas said: All that generation who heard the voice of the Holy One, blessed be He, on Mount Sinai, were worthy to be like the ministering angels, so that insects had no power over them. They did not experience pollution in their lifetime, and at their death neither worm nor insect prevailed over them. Happy were they in this world and happy will they be in the world to come, and concerning them the Scripture says, "Happy is the people, that is in such a case" (Ps. 144:15).

(Devarim, Ibid.) "he (Benjamin) shall rest securely upon Him": And there is no "security" but in "dwelling," viz. (Ezekiel 34:25) "And they will dwell securely in the desert and sleep in the forests."
