וַהֲקִימֹתִ֥י לִי֙ כֹּהֵ֣ן נֶאֱמָ֔ן כַּאֲשֶׁ֛ר בִּלְבָבִ֥י וּבְנַפְשִׁ֖י יַעֲשֶׂ֑ה וּבָנִ֤יתִי לוֹ֙ בַּ֣יִת נֶאֱמָ֔ן וְהִתְהַלֵּ֥ךְ לִפְנֵֽי־מְשִׁיחִ֖י כָּל־הַיָּמִֽים׃
Y yo me suscitaré un sacerdote fiel, que haga conforme á mi corazón y á mi alma; y yo le edificaré casa firme, y andará delante de mi ungido todo los días.

And with Evyosor the kohein. He was dismissed from the priesthood at the time when Dovid escaped from Yerusholayim on account of Avsholom, when he [Evyosor] consulted the Urim and Tumim and was unsuccessful as it is stated, “And Evyosor went up.”16II Shmuel 15:24. He [Evyosor] was a descendant of Eili. And he knew that he would not serve in the days of Shlomo, for it was stated to Eili, “And I will appoint for Myself a faithful kohein... and he will serve before My anointed one...”17I Shmuel 2:35. He [Evyosor] wanted that this one [Adoniyah become king] through his assistance.18So that Adoniyahu would listen to him when he became king and would restore him to his previous position of Kohein Gadol.

That He had spoken concerning the house of Eili. [As it is stated,] “And I will appoint for Myself a faithful kohein,”14I Shmuel 2:35. [and] “and you will see a rival in My dwelling place, etc.”15Ibid. 2:32. Once [the Tabernacle at] Shilo was destroyed, there was no house worthy of service to the Holy One Blessed Is He, but now that the Beis Hamikdosh will be built, the Holy One Blessed Is He, fulfilled His word to banish Eili’s descendants.16Evyosor was Eili’s great great grandson. See I Shmuel 14:3, 22:20.
