Le Deutéronome 10:6 Commentaire : Rashi, Chizkuni, Da'at Zekenim & Ramban

ובני ישראל נסעו מבארת בני יעקן מוסרה AND THE CHILDREN OF ISRAEL JOURNEYED FROM BEEROTH OF THE CHILDREN OF JAAKAN TO MOSERA — What has this matter to do with what has been related here? Further: Did they indeed journey from Beeroth of the children of Jaakan to Mosera; did they not come from Mosera to Beeroth of the children of Jaakan, as it is said, (Numbers 33:31) “And they journeyed from Moseroth, [and they encamped in Bene Jaakan]”? And further: it states here, “There (at Mosera) did Aaron die”. But did he not die at Mount Hor? Go and count and you will find that there are eight stations from Mosera to Mount Hor! — But really this also is part of the reproof offered by Moses. In effect he said, “This, also, ye did: when Aaron died on Mount Hor at the end of forty years and the clouds of Divine Glory departed, ye feared war with the king of Arad and you appointed a leader that ye might return to Egypt, and ye turned backwards eight stages unto Bene Jaakan and hence to Mosera. There the sons of Levi fought with you, and they slew some of you, and you some of them, until they forced you back on the road along which you had retreated. From there (Mosera) ye returned to Gudgodah, — that is identical with Hor Hagidgod (Numbers 33:32).

The Children of Israel journeyed from Beeroth-bene-jaakan, meaning do not say Aaron died at the Golden Calf affair at the beginning of the forty years and my[Moses] prayer didn't help him, because ultimately [as the pasuk shows us] Aaron died at the end of the forty years at Mount Hor at the same time as The Children of Israel journeyed from Beeroth-bene-jaakan after arriving there from Moserah.

ובני ישראל נסעו מבארות בני יעקן, and the Children of Israel had journeyed from Beer Yaakon;” according to the plain meaning of the text Mossera is not the same place as Mosserot in Numbers 33,3, and bney yaakon is not the same as yaakon in that chapter. Between these two locations was hor hahar where Aaron had died. The correct meaning of the text here is: the Children of Israel journeyed from beerot bney yaakon on the way to Mossera, and they encountered hor hahar on their journey, the place where Aaron died.
