Verse 25. - Bring them up unto Mount Hor. It can scarcely be doubted that the object of this command was to produce a deeper effect upon the people. The whole multitude would be able to see the high priest, whose form had been so familiar to them as long as they could remember anything, slowly ascending the bare sides of the mountain; and they knew that he went up to die. The whole multitude would be able to see another and a younger man descending by the same path in the same priestly robes, and they knew that Aaron was dead, and that Eleazar was high priest in his room. Death is often most striking when least expected, but there are occasions (and this was one) when it gains in effect by being invested in a certain simple ceremonial.
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?
and bring them up unto Mount Hor; to the top of it, they being now at the foot of it, where the people of Israel lay encamped.
