Musar su Malachia 3:23

This is what our sages had in mind when they said: "Pinchas is none other than the prophet Elijah" (Baba Metzia 114), for G–d has said: "Lo, I will send Elijah to you before the coming of the awesome fearful day of the Lord" (Malachi 3,23). Targum Yonathan renders Exodus 4,13, where Moses declines the mission of leading the Jewish people with the words שלח נא ביד אשר תשלח, "Please make someone else Your agent," as: "Send Pinchas to be that leader," (seeing that he is ready and willing to accept this mission of the future, being identical with Elijah). We need to understand what prompted Yonathan ben Uzziel to derive this conclusion based on the verse in Exodus quoted.

It is written in Sodei HaRazim (by the author of the Roke’ach): Regarding all the transgressions in the Torah, if a person commits them in private, the prophet Eliyahu will not reveal them. But if someone violates a ban (cheirem) then he does announce it and reveal it. For it is written, “I am going to send you Eliyahu the prophet, etc.” (Malachi 3:23). And it is written immediately afterwards, “And I will strike the land [with] a ban.”
