Explanation of מזמור שירו לה׳ שיר חדש, the fourth פרק of תהלים in קבלת השבת, where we describe the continuous progression of the development of the world in attaining the close connection to ה׳ during the גאולה process. We focus on the reaction of the world to ה׳'s גילוי שכינה as well as the impact the Jewish nation had with the world throughout history to bring mankind to this point.
