Medrash: Pinchos the son of Elozor the son of Aharon etc., Pinchos he is Eliyohu, Hashem said, “You made peace between Klall Yisroel and their Father in Shomayim (heaven), Chayechoh (your life), You will in the future be sent to make peace. As it says, (Malachi 3:23) “Behold I will send to you Eliyohu, the prophet and He will return the hearts of the children to their fathers etc.”
This needs explanation, “I seem to say with the help of Hashem Yisborach, that the Possuk wants to explain the Yichus (genealogy) “the son of Aharon” as numerous times it says just “Elozor Hakohen” and all is known”. Therefore, we must explain here the “Midah Keneged Midah” (attribute for similar action) Brisi Sholom (my covenant of peace), since he was “Ben (the son of) Aharon Hakohen”, He was from the students of Aharon Hakohen, who loves peace.
