Numbers 20:27 WBT

²⁵  Take Aaron and Eleazar his son, and bring them up to mount Hor:

²⁶  And strip Aaron of his garments, and put them upon Eleazar his son: and Aaron shall be gathered [to his people], and shall die there.

²⁷  And Moses did as the LORD commanded: and they ascended mount Hor in the sight of all the congregation.

²⁸  And Moses stripped Aaron of his garments, and put them upon Eleazar his son; and Aaron died there on the top of the mount: and Moses and Eleazar came down from the mount.

²⁹  And when all the congregation saw that Aaron was dead, they mourned for Aaron thirty days, [even] all the house of Israel.
