22 They traveled from Kadesh: and the children of Israel, even the whole congregation, came to Mount Hor. 23 Yahweh 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 children of Israel, because you rebelled against my word at the waters of Meribah. 25 Take Aaron and Eleazar his son, and bring them up to Mount Hor; 26 and strip Aaron of his garments, and put them on Eleazar his son: and Aaron shall be gathered to his people, and shall die there.” 27 Moses did as Yahweh commanded: and they went up into Mount Hor in the sight of all the congregation. 28 Moses stripped Aaron of his garments, and put them on Eleazar his son; and Aaron died there on the top of the mountain: and Moses and Eleazar came down from the mountain. 29 When all the congregation saw that Aaron was dead, they wept for Aaron thirty days, even all the house of Israel.

Commentary on Numbers 20:22-29
(Read Numbers 20:22-29)
God bids Aaron prepare to die. There is something of displeasure in these orders. Aaron must not enter Canaan, because he had failed in his duty at the waters of strife. There is much of mercy in them. Aaron, though he dies for his transgression, dies with ease, and in honour. He is gathered to his people, as one who dies in the arms of Divine grace. There is much significancy in these orders. Aaron must not enter Canaan, to show that the Levitical priesthood could make nothing perfect; that must be done by bringing in a better hope. Aaron submits, and dies in the method and manner appointed; and, for aught that appears, with as much cheerfulness as if he had been going to bed. It was a great satisfaction to Aaron to see his son, who was dear to him, preferred; and his office preserved and secured: especially, to see in this a figure of Christ's everlasting priesthood. A good man would desire, if it were the will of God, not to outlive his usefulness. Why should we covet to continue any longer in this world, than while we may do some service in it for God and our generation?
