What is said in the verse, "Zion shall be redeemed with justice, and they that return by righteousness" suggests that Zion was redeemed by First World War, when an explicit judgement and law issued by all nations decreed that it [Zion] was to be given to the Nation of Israel, "justice" referring to the judgement issued by the nations. "They that return" – meaning the return and ingathering of the exiles – will, however, take place through charity, that is, merit and good deeds… We must each try to make a vigilant effort to avoid sin and to increase in good deeds, charity in particular, so that we may hope and expect to deserve that the declaration about to be issued by the heads of nations will favor the people of Israel and the ingathering of the exiles.
