Numbers 27:12

Go up this Avarim Mountain. Why is this placed here? When the Holy One, Blessed is He, said [to Moshe], “give them. . .,” he said, ‘God commanded me to give them the hereditary property. Perhaps the decree was abrogated, and I may enter the land.’ The Holy One, Blessed is He, said to him, “My decree remains in place.” Another interpretation: When Moshe entered the inheritance given to the sons of Gad and Reuven, he rejoiced, and said, ‘It seems that the vow regarding me was abrogated.’ This is comparable to a king who decreed that his son could not enter the doorway to his palace. He [the King] entered the gateway, and he [the son] followed, [he entered] the courtyard, and he followed, [he entered] the anteroom, and he followed. When he was about to enter the chamber, he [the king] said to him, ‘My son, from here and onward, you are forbidden to enter.’

And the Lord said to Mosheh, Go up to this mount, of Abaraee, and survey the land which I have given to the children of Israel.

GET THEE UP INTO THIS MOUNTAIN OF ABARIM. The name of this mountain was Mount Nebo, as is stated explicitly in the sections of Ha’azinu, and V’zoth Habrachah;, 34:1. but it is [here] called the mountain of Abarim [meaning “fords”] because it is situated by the fords of the Jordan, from which one passes over into the land of Canaan, as it says here, that is over against Jericho,, (32:49; 34:1). The word “here” in Ramban cannot be explained literally, since in this section here, the phrase over against Jericho is not found. It must therefore refer to the verse in Ha’azinu and V’zoth Habracha which Ramban has just referred to. and it was from there that they [actually] crossed over the Jordan, as it is said, And the people came up out of the Jordan … and encamped in Gilgal, on the east border of Jericho. Now this [statement get thee up] is not a commandment which the Holy One, blessed be He, commanded Moses to fulfill now, for if so he would have had to go up there at once [and we do not find that he did so], but it means: “you shall go up into the mountain of Abarim and shall behold the Land [but you shall not enter it].” For since He had commanded Moses, Unto these the Land shall be divided, He informed him that “it will not be divided by you, but you shall go up into the top of the mountain of Abarim before Israel journeys away from the land of Moab, and you will die therein, and all you will have of the Land will be the sight thereof.” Similarly [Verse 18 which says] Take thee Joshua the son of Nun, means that “when your time [to die] comes, you shall take Joshua,” [but is not a command to do so now]. And Scripture completed [this episode] by saying that Moses did so whole-heartedly,, Verses 22-23. This refers to the fact that although Moses was only commanded (in Verse 18) to lay “his [single] hand upon him,” he laid his ‘hands’ upon him, which shows that he appointed his successor whole-heartedly, although he knew that he was now to die. and this is the [same] act which is mentioned at [the time of] Moses’ departure [from the world], when he and Hoshea the son of Nun spoke [the words of] the Song., 32:44. Thus Scripture points out there that Moses and Joshua said the Song together, with equal enthusiasm and equally whole-heartedly.
