Numbers 33:37-44

They traveled from Kadesh and camped at Mount Hor  on the edge of the land of Edom. At the LORD’s command, the priest Aaron climbed Mount Hor and died there on the first day of the fifth month in the fortieth year after the Israelites went out of the land of Egypt.  Aaron was 123 years old when he died on Mount Hor. At that time the Canaanite king of Arad, who lived in the Negev in the land of Canaan,  heard the Israelites were coming. They traveled from Mount Hor and camped at Zalmonah. They traveled from Zalmonah and camped at Punon. They traveled from Punon and camped at Oboth.  They traveled from Oboth and camped at Iye-abarim on the border of Moab.
