Rabbi Sacks, zt’’l, had prepared a full year of Covenant & Conversation for 5781, based on his book ‘Lessons in Leadership.’ It should have been a day of joy. The Israelites had completed the Mishkan, the Sanctuary. For seven days Moses had made preparations for its consecration.[1] Now on the eighth day—the first of Nisan—one year to the day since the Israelites had received their first command two weeks prior to the Exodus (Ex. 40:2)—the service of the Sanctuary was about to begin (Lev. 9:1-24). The Sages say that in Heaven it was the most joyous day since Creation (Megillah 10b).
