Numbers 20:22-29 - Aaron Dies
22 And the sons of Israel, the whole congregation, pulled up stakes from Kadesh and came to Mount Hor. 23 And Jehovah spoke to Moses and Aaron in Mount Hor, by the border of the land of Edom, saying, 24 Aaron shall be gathered to his people. For he shall not enter into the land which I have given to the sons of Israel, because you rebelled against My word at the Waters of Strife. 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 Jehovah commanded. And they went up into 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 in the top of the mount. And Moses and Eleazar came down from the mountain. 29 And when all the congregation saw that Aaron was dead, they mourned for Aaron thirty days, all the house of Israel.
