Rashi Commentary
'ויעש כאשר צוה וגו AND HE DID AS [THE LORD] COMMANDED [MOSES] etc. — When the next Day of Atonement arrived he (Aaron) did everything as is here set forth in order. And Scripture only states this in order to declare the praise of Aaron — that he did not attire himself with them (the official garments) for his own aggrandisement, but as one who was executing the ordinance of his King (Sifra, Acharei Mot, Chapter 8 10).
