משך חכמה — לא יסורו ממנו

Q — Why must the staves of the Aron uniquely never be removed (unlike those of the שולחן or המזבח) — what does this teach?

A — The Aron carries its bearers — it does not need to be carried. When it rests in the אוהל מועד the staves are obviously useless; the chiddush is that they are equally unnecessary when it is being borne — yet they remain permanently, mirroring how the daytime menorah lighting (which obviously isn't for light) teaches that the nighttime lighting also isn't for light but for עדות שהשכינה שורה בישראל. A clearly superfluous act reveals the true purpose of the parallel act.
