"Mount Avarim": It has four names: Mount Avarim, Mount Nevo, Hor Hahar, Rosh Hapisgah. And why is it called "Mount Avarim"? Because there are buried there three who died without transgression ("aveirah") — Moses, Aaron, and Miriam.
"which is in the land of Moav, facing Jericho, and see": R. Eliezer said: (The angel) Metatron pointed out all of Eretz Yisrael to Moses with his finger: "Until here is the boundary of Ephraim"; "until here is the boundary of Menasheh." R. Yehoshua says Moses by himself saw it. How so? The L-rd placed power in Moses' eyes and he saw from one end of the world to the other.
