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 mount. (Numbers 20:28)
This Moses did, acting for God according to His command, and as a sign of the transference of the priestly office, which continued despite the death of the holder.
Aaron died there.
The date of Aaron’s death, and his age, 123 years, are given in ch. 33:38, 39. The death of Aaron emphasized the imperfection of the Levitical priesthood in respect to its changeableness. Paul speaks of the contrast between it and Christ’s priesthood in this respect (Heb. 7:24). According to Deut. 10:6, Aaron was buried at Mosera (see on v. 25).
