Numbers 20:24-26

²⁴“It is time for Aaron to die EUP. He will not enter the land that I am giving to you Israelis, because the two of you disobeyed me when I told you to speak to the rock to cause the water to flow at Meribah.

²⁵Now you, Moses, take Aaron and his son Eleazar up on Hor Mountain.

²⁶There you must remove Aaron's robes that he wears when he does the work of a priest, and put them on his son, Eleazar. Aaron will die up there.”
