Numbers 20:22-29
Aaron dies
22 All the Israelites went from Kadesh to Hor mountain. 23 When they were there, at the border of Edom's land, the Lord spoke to Moses and Aaron. 24 He said, ‘Aaron will soon die. He will not go in to the land that I am giving to the Israelites. That is because you both refused to obey me at Meribah. 25 Moses, you must take Aaron and his son Eleazar to climb up Hor mountain. 26 Take the priest's clothes from Aaron and put them on Eleazar. Aaron will die there.’
27 Moses did what the Lord told him to do. Moses, Aaron and Eleazar climbed up Hor mountain, while the Israelites watched. 28 Moses took the priest's clothes from Aaron and he put them on Eleazar. Then Aaron died there, at the top of the mountain. Moses and Eleazar walked back down the mountain. 29 The Israelites wept for 30 days because Aaron died.
20:28Moses and Eleazar came down from Hor mountain. The people saw that Eleazar was wearing the clothes of the leader of the priests. So they knew that Aaron was dead.
