Our Sages identify Pinchas with Elijah the Prophet, the herald of the Redemption. They explain that Elijah’s function will be more than that of a bearer of news. He will also help inspire love and harmony that will make Redemption a reality. Similarly, Maimonides writes that Elijah will come “solely to spawn peace.” Spreading peace will encourage Moshiach’s coming, creating a setting wherein he will desire to enter.
This also serves as a lesson to all of us. Working to generate harmony will serve as a catalyst for the ultimate harmony Moshiach will introduce in the world.
