New American Standard Bible

²⁷ So Moses did just as the Lord had commanded, and they went up to Mount Hor in the sight of all the congregation. ²⁸ And after Moses stripped Aaron of his garments and ^(A)put them on his son Eleazar, ^(B)Aaron died there on the mountain top. Then Moses and Eleazar came down from the mountain. ²⁹ When all the congregation saw that Aaron had died, the whole house of Israel wept for Aaron for thirty ^(C)days.
