פירוש על שמואל א 2:30

I had indeed decreed. Twice I assigned greatness to the sons of Isomor: Concerning the sons of Gershon and the sons of Merori, it is stated, "Under the direction of Isomor, the son of Aharon the kohein."²³ Bamidbar 4:33. And Eili was one of the descendants of Isomor. This [explanation] I saw in Midrash Shmuel. I have, however, heard a more fitting explanation: "I had indeed decreed that your family and your father's family…" Originally I made Elozor the kohein to serve as kohein gadol, as it is stated, "remove Aharon's vestments, [and dress Elozor his son in them]."²⁴Ibid., 20:26. However, at the time of the concubine,²⁵ See Shoftim Chapters 19-21. Yisroel divested themselves of most mitzvos. And who was to blame [for this]? Pinchas and his associate kohanim, who should have gone around from city to city to reprove them. I therefore took the kehunah gedolah away from them, and gave it to you, for you are of Isomor's descendants, and I said, that they shall walk before Me forever; for when greatness is assigned to a person, it is assigned to him and to his generations forever.

For I honor those who honor Me. Pinchas' descendants who honored Me at Shittim.²⁶Bamidbar 25:7-8. And this happened in the days of Shlomo, that when the Temple was built, Shlomo dismissed Evyosor from being a kohein [gadol] to 'ה, fulfilling the word of 'ה which He had spoken concerning Eili's family.²⁷ I Melochim 2:27. And Tzadok became the kohein gadol, because he was of Pinchas' descendants; he is so listed in the genealogical records in Divrei Hayomim.²⁸I Divrei Hayomim 6:35-38.

And those who dishonor Me will be cursed. By. themselves, when I will withdraw Myself from them.²⁹Referring to Eili’s sons from whom the kehunah gedolah would be removed in the time of Shlomo Hamelech.
