G-d in His mercy will remember that they were always His people, and that they were His servants, who loyally tolerated the afflications and oppression of exile.
(Deuteronomy 32:26)

All the curses in the Torah applied only before we went into exile. But after we were in exile in the lands of our enemies, the works of our hands were not cursed, nor our cattle and sheep, nor our vineyards and olive trees and what we plant in the field. Rather, we will live on a similar level to the nations among whom we live, or even better than them, since His mercy is upon us, because our dwelling in exile comes with the promise
