Moshe was commanded (Shemos 40:9-15) to anoint the Mishkan and its Kelim, and only afterwards to bathe, dress and anoint Aharon and his sons. Why did Moshe bathe and dress Aharon and his sons before anointing the Mishkan and its Kelim?

Ramban, Moshav Zekenim: There, the Torah wanted to discuss the actions to Aharon and his sons together. Really, he did like it says here; it was proper that Aharon and his sons be ready to be anointed immediately after anointing the Mishkan and its Kelim.
