Aaron Dies on Mount Hor

Numbers 20:22-29

They traveled from Kadesh, and the children of Israel, even the whole congregation, came to Mount Hor. The LORD spoke to Moses and Aaron in Mount Hor, by the border of the land of Edom, saying, “Aaron shall be gathered to his people; for he shall not enter into the land which I have given to the children of Israel, because you rebelled against my word at the waters of Meribah. Take Aaron and Eleazar his son, and bring them up to Mount Hor; and strip Aaron of his garments, and put them on Eleazar his son. Aaron shall be gathered, and shall die there.” Moses did as the LORD commanded. They went up onto Mount Hor in the sight of all the congregation. Moses stripped Aaron of his garments, and put them on Eleazar his son. Aaron died there on the top of the mountain, and Moses and Eleazar came down from the mountain. When all the congregation saw that Aaron was dead, they wept for Aaron thirty days, even all the house of Israel.

Deuteronomy 10:6

(The children of Israel traveled from Beeroth Bene Jaakan to Moserah. There Aaron died, and there he was buried; and Eleazar his son ministered in the priest’s office in his place.
