Tafsiran Imamat 21:8: Rashi, Alshekh, Kitzur Ba'al HaTurim & Ramban

וקדשתו THOU SHALT SANCTIFY HIM — even against his will; it means that if he is not willing to divorce the woman whom he had illegally married flog him (מלקות ארבעים) and chastise him (מכות מרדות) until he divorces her (Sifra, Emor, Chapter 1 13; Yevamot 88b).

The bread of their God. Their holiness is because they offer the bread of Hashem and not due to their own essence. In this aspect they have no advantage over Israelites, for regarding the kohanim the Torah writes only קדשים without the vav. Kodesh is written fully with the vav only concerning Hashem (v. 8): “For I, Adonoy, am holy [קודש], Who makes you holy.” Furthermore, I am not making any leniency for them because of their holiness, and on the contrary (v. 9), “The daughter of a kohein … shall be burned with fire” (Alsheich).

You shall make him holy. Three times holiness is mentioned in the verse: To [hint that the kohein should] speak first, that he should bless first, and we should give him the nice portion first.

קדש יהיה לך HE SHALL BE HOLY UNTO THEE — holy unto thee: treat him with sanctity (as someone holy) — that he should be the first in all holy matters (e. g., the reading of the law) and that he should have the first right to recite the benedictions at a meal (המוציא and ברכת המזון) (Gittin 59b; cf. Rashi on Nedarim 62b).
