Levi Yitzchok of Berditchev

[2] Levi Yitzchok was known as the "defense attorney" for the Jewish people ("Sneiguron Shel Yisroel"), because he would intercede on their behalf before God.

Known for his compassion for every Jew, he was one of the most beloved leaders of Eastern European Jewry.

Levi Yitzchak was born in 1740 CE (5500 in the Jewish calendar) to Rabbi Meir (who was the Av Beit Din (head of a rabbinical court) of Zamosc) and Sarah-Sasha Ruskov in Husakiv, now in Yavoriv Raion, Lviv Oblast (region) of Ukraine.

[6] Levi Yitzchok composed some popular Hasidic religious folk songs, including A Dude'le and "The Kaddish of Rebbe Levi Yitzchok (A din Toyre mit Gott)."

One of Levi Yitzchok's grandsons married the daughter of Dovber Schneuri, the second Chabad-Lubavitch rebbe and the first to live in Lubavitch.
