レビ記 21:24

וידבר משה AND MOSES TOLD this command, 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).

וַיְדַבֵּ֣ר מֹשֶׁ֔ה אֶֽל־אַהֲרֹ֖ן וְאֶל־בָּנָ֑יו וְאֶֽל־כׇּל־בְּנֵ֖י יִשְׂרָאֵֽל׃ {פ}

And Moshe spoke to Aharon, and to his sons, and to all the children of Yisra᾽el.
