"It's time for Aaron to be gathered into the company of his ancestors. He will not enter the land I am giving to the People of Israel because you both rebelled against my orders at the Waters of Meribah.
So take Aaron and his son Eleazar and lead them up Mount Hor.
Remove Aaron's clothes from him and put them on his son Eleazar. Aaron will be gathered there; Aaron will die."
Moses obeyed God's command. They climbed Mount Hor as the whole congregation watched.
Moses took off Aaron's clothes and put them on his son Eleazar. Aaron died on top of the mountain. Then Moses and Eleazar came down from the mountain.
The whole congregation, getting the news that Aaron had died, went into thirty days of mourning for him.
