Commento su Levitico 21:24

וידבר משה AND MOSES TOLD this command,

To warn the court. Because if not so, what have Yisroel to do with the warning of the kohanim?

ואל כל בני ישראל, “as well as to all the Children of Israel.” They are warned not to entrust their offerings to priests who are afflicted with blemishes.

אל אהרן ואל בניו ואל כל בני ישראל UNTO AARON AND UNTO HIS SONS AND UNTO ALL THE CHILDREN OF ISRAEL — He told it to the Israelites although they were not directly concerned with these commands in order to admonish the court regarding the priests (i. e. that the authorities should watch over the sanctity of the Sanctuary and prevent priests with a bodily blemish from officiating) (Sifra, Emor, Chapter 3 12).
