Kommentar zu Wajikra 22:9

ושמרו את משמרתי THEY SHALL THEREFORE KEEP MY CHARGE — not to eat the heave-offering (as mentioned in v. 7) whilst they are in a state of bodily uncleanness (Sanhedrin 83a).

אני ה' מקדשם, I have sanctified them (the items sanctified as donations by the ordinary Israelites) It is therefore appropriate that priests who treat these sanctified objects with disdain (as if they were profane), be punished for desecrating them.

Not to eat. Explanation: “They shall keep” is referring to [what is written] earlier where it was discussing terumah, as Rashi explained above.

ומתו בו LEST THEY DIE THEREBY — This phrase teaches us that this means death through Heaven (not through the sentence of the court) (cf. Sanhedrin 83a).

At the hands of Heaven. Re’m asks: From where do we derive that this is death at the hands of Heaven? Is there not a rule that every death mentioned in the Torah without specification is [death by] strangulation? He leaves this question unanswered. The answer is: The death spoken of here must be at the hand of Heaven, because kodshim are more severe than terumah, since [unlike terumah] kodshim are forbidden [for someone who went to mikveh for his impurity] to be eaten kodshim at [after] sunset. Yet even so, if someone ate kodshim when ohine’s body was impure, heone is not liable for death at by the hand of man, because we derive the eating of kodshim from entering of the Sanctuary with a hekesh, as stated above in parshas Ki Tazria (12:4). And entering the Temple in a state of impurity is punished by koreis as it is written (Bamidbar 12:20), “That soul will be cut off from the community; for he defiled the Sanctuary of Hashem.” [If so], how much more is the lenient terumah not be liable for death by the hand of man. Another answer is: Rashi explained earlier in parshas Ki Tazria (ibid), that [the words] “anything holy” come to include terumah. This indicates that the death mentioned in terumah is koreis, similar to [the punishment for] eating kodshim. Another answer is that the verse indicates this by writing “And die because of it, etc., I am Hashem.” Why add “I am Hashem”? This must refer to the beginning of the verse where it states “And die because of it, etc.,” and it means, “I am Hashem,” Who will surely punish and kill him. This is death by the hand of Heaven.
