Deuteronomy 10:6

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).

וּבְנֵ֣י יִשְׂרָאֵ֗ל נָ֥סְע֛וּ מִבְּאֵרֹ֥ת בְּנֵי־יַעֲקָ֖ן מוֹסֵרָ֑ה שָׁ֣ם מֵ֤ת אַהֲרֹן֙ וַיִּקָּבֵ֣ר שָׁ֔ם וַיְכַהֵ֛ן אֶלְעָזָ֥ר בְּנ֖וֹ תַּחְתָּֽיו׃

And the children of Yisra᾽el took their journey from Be᾽erot-bene-ya῾aqan to Mosera: there Aharon died, and there he was buried; and El῾azar his son ministered in the priest’s office in his place.
