What did the anointing of the Mizbach ha'Olah and all its Keilim and their sanctification represent?
Targum Yonasan: It represented Aharon and his sons, and Eliyahu the Kohen Gadol who will be sent at the end of the Galus.
Bearing in mind that the Mize'ach ha'Olah was in the Chatzer, why does the Torah refer to it as 'Kodesh Kodshim'?
Ramban #1, Moshav Zekenim #1: Because they offered up on it Kodshei Kodshim as well. 1
Ramban #2, Moshav Zekenim #2: Because it rendered what touched it Kodesh. 2
