Numbers 20:27-29

Revised Standard Version

²⁷ Moses did as the Lord commanded; and they went up Mount Hor in the sight of all the congregation. ²⁸ And Moses stripped Aaron of his garments, and put them upon Elea′zar his son; and Aaron died there on the top of the mountain. Then Moses and Elea′zar came down from the mountain. ²⁹ And when all the congregation saw that Aaron was dead, all the house of Israel wept for Aaron thirty days.
