– Moshe Rabeinu redeemed the Jews from Egypt and our Sages declare, “He was the first redeemer and he will be the ultimate Redeemer.”
Yisrael stands for Yisrael the Baal Shem Tov, the founder of Chassidic teaching. The spreading of the ‘wellsprings’ of this teaching brings the Redemption. And ultimately, the Mashiach will be a descendant of David, the first anointed king.
From the Rebbe’s talk on Shabbos Parshas Yisro, 5752(1992).
