Quotation על ישעיהו 45:18

It is from the roots of this commandment (i.e the reason behind this commandment) that the world should be settled (Gittin 41b) because God wants the world to be settled, as it says (Isaiah 45:18), "I did not create it for naught, but [rather] formed it for habitation." This is a great commandment, through which all the commandments are observed, as [the Torah] was given to people and not to the ministering angels (Berakhot 25b).
