Musar su Osea 2:2

We find hints of such a future in the statement of Rabbi Yochanan in Tractate Pesachim 88a: "The day when the exiled will be gathered in is as great as the day on which heaven and earth were created, as described in Hosea 2,2: 'The people of Yehudah and the people of Israel will assemble together and appoint a single head [leader] for themselves; they shall rise from the ground, for marvelous shall be the day of Jezreel.'" It is also written: "It was evening it was morning, one day" (Genesis 1,5) [the day of Jezreel is a reference to the first day in Genesis]. When the true ingathering of the exiles takes place, at the time our righteous Messiah appears, Creation itself will renew itself; a new "light" will emerge. At that time body and soul will be able to fuse. Also the earth itself, though purely matter, will be full of knowledge; thus together with the perfection existing "down here," the full extent of G–d's blessings from "above" will be experienced, so that body and soul may live forever. At the time of creation man was described as אדם ביקר בל ילין, "unable to last the night despite his precious qualities." (Psalms 49,13). Man had corrupted his potential so that mortality was decreed upon him. G–d however, has given us the Torah by means of which we can acquire the merit we need to assure us of an everlasting future. He has given us commandments which teach us that this is indeed the case, for they provide the clue to the eventual immortality of the body, in addition to that of the soul. At the present time, the "eternity" of man's body is restricted to man as a species. דור הול ודור בא, "one generation goes and another comes in its place" (Kohelet 1,4). Man's soul, however, enjoys eternal life even in these times, for every individual soul survives the death of its body. Whereas nowadays the body's "life" is considered as incidental, its death is permanent; the soul's life is however, eternal, its "death" being merely incidental [apparent, seeing it can no longer function within the body. Ed.].
