Moseroth - Situation unknown. In Deuteronomy 10:6 it is said that the Israelites took their journey from Beeroth, the wells of the children of Jaakan, to Mosera, and there Aaron died. If so, Mosera, Moseroth, and Hor, must be different names of the same place; or Moseroth, or Mosera, must have been some town or village near Mount Hor, for there Aaron died. See Numbers 33:38.
Stat. 27.

And they departed from Hashmonah, and encamped at Moseroth. Thirty two miles from Hashmonah. In Deuteronomy 10:6 it is called Mosera; and according to the account there, they came hither from the following place, Benejaakan; probably they went first thither from Hashmonah, and then from Mosera or Moserot, and so to Benejaakan again, going backwards and forwards, so Jarchi; the distance of the two places was twenty four miles; for the further reconciliation this; see Gill on Deuteronomy 10:6 and the Samaritan version there.
