This lecture covers Bamidbar Chapter 20, marking the transition to the 40th year in the desert as the generation prepares to enter the Land of Israel. The chapter records Miriam’s death, the incident at Mei Merivah where Moshe strikes the rock instead of speaking to it—resulting in God’s decree that he will not enter the Land—and concludes with the failed diplomatic mission to Edom and Aharon’s death at Mount Hor, where his son Elazar receives the priestly garments in succession.
