מוסר אויף דניאל 12:10

Moreover, the first redemption was only temporary, [in that it was followed by other exiles,] as explained in holy books, however this final redemption will conclude all exiles and there will not be any further exiles. As a result, all the faults of Israel from the day they became a nation, must be rectified, and through the lengthiness of the exile, it all is rectified. Furthermore, the exile itself is like a great smelting furnace that separates the bad from the good, as stated at the end of the book of Daniel,¹⁵Daniel 12:10 “Many will be clarified and purified and refined etc.” All this requires much time.
