A long letter handwritten and signed by Rebbe Mordechai Rokeach the Bilgoraj Rabbi, in the name of his brother Rebbe Aharon of Belz. With the stamp of Rebbe "Aharon Rokeach of Belz". [Tel Aviv, autumn 1948]. In a letter sent to London to their relative Rebbe Yissachar Ber HaLevi Rothenberg [Av Beit Din of Wodzisław, later moved to Brooklyn], the Bilgoraj rabbi writes of the state of health of his brother Rebbe Aharon of Belz and notes that the gabai R' Hillel Wind "wrote a kvittel for you and I have given it to my brother the rebbe…". He continues with a specific blessing for each family member. Further he writes: "I have also given my brother the Rebbe one pound which he sent for…and blesses him with salvation…we should merit giving and receiving only good news… Mordechai son of the Rebbe of Belz". The Bilgoraj rabbi, Rabbi Mordechai Rokeach (1901-1950, Encyclopedia L'Chassidut Vol. 3, 224-225), son of Rebbe Yissachar Dov of Belz. After the death of his father, was appointed Rabbi and Av Beit Din of Bilgoraj and was completely subservient to his older brother who was the Rebbe. During the Holocaust, he traversed many places to reach his brother the Rebbe and together they wandered from place to place until by miracle, they managed to flee to Hungary and from there to Eretz Israel. After their Aliya, Rabbi Mordechai became one of the most prominent figures in Eretz Israel and assisted his brother in re-establishing the Belz Chassidism in Eretz Israel. In 1946, after he was informed that his wife and children were all murdered in the Holocaust, he remarried and died a short while later at a young age. His only son from this marriage was the present Belz Rebbe, who was born on Sunday the 7th of Shevat 1948. Aerogram, [2] pages. 19 cm. Approximately 35 handwritten lines. Good condition. Few creases.
