John Wesley on Numbers 20:28

And Moses stript Aaron - And Death will strip us. Naked we came into the world: naked we must go out. We shall see little reason to be proud of our cloaths, our ornaments, or marks of honour, if we consider how soon death will strip us of all our glory, and take the crown off from our head! Aaron died there - He died in Mosera, Deu 10:6. Mosera was the general name of the place where that station was, and mount Hor a particular place in it. Presently after he was stript of his priestly garments, he laid him down and died. 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 God and our generation some service?
