Numbers 20:22-29

²²And they departed from Cades; and the children of Israel, even the whole congregation, came to Mount Or.

²³And the Lord spoke to Moses and Aaron in mount Or, on the borders of the land of Edom, saying,

²⁴Let Aaron be added to his people; for ye shall certainly not go into the land which I have given the children of Israel, because ye provoked me at the water of strife.

²⁵Take Aaron, and Eleazar his son, and bring them up to the mount Or before all the congregation;

²⁶and take Aaron's apparel from off him, and put it on Eleazar his son: and let Aaron die there and be added to his people.

²⁷And Moses did as the Lord commanded him, and took him up to mount Or, before all the congregation.

²⁸And he took Aaron's garments off him, and put them on Eleazar his son, and Aaron died on the top of the mountain; and Moses and Eleazar came down from the mountain.

²⁹And all the congregation saw that Aaron was dead: and they wept for Aaron thirty days, even all the house of Israel.
