36They set out from Ezion-geber and camped at Kadesh in the Wilderness of Zin.
37They set out from Kadesh and camped at Mount Hor, on the outskirts of the land of Edom.
38At the LORD’s command, Aaron the priest climbed Mount Hor and died there on the first day of the fifth month, in the fortieth year after the Israelites had come out of the land of Egypt.
