Letter from Rebbe Sinai Halberstam of Zhmigrod - Blessings for a Complete Recovery
Letter on a postcard from Rebbe Sinai Halberstam Rabbi of Zhmigrod. "Wysowa" (Wysowa-Zdrój, Poland), [ca. 1934].
In this letter, addressed to R. Chaim Shaul Schöndorf in Nuremberg, the Rebbe's extends his blessings and encouragement for a "complete and speedy recovery from Heaven, and may he still merit to recount in full health of all his tribulations, and inform me of good tidings…". Most of the letter is written by a scribe, though the final eight lines are handwritten and signed by the Rebbe (on the verso of the postcard): "Who seek his wellbeing wholeheartedly, and blesses him from the depth of my heart with the above blessings, and entreat G-d to fulfill my blessings in him… Who awaits his speedy recovery, Sinai Halberstam".
Rebbe Sinai Halberstam of Zhmigrod (1871-1941), son of Rebbe Baruch of Gorlitz (Gorlice) and grandson of R. Chaim of Sanz (Nowy Sącz), was named Sinai at the behest of his grandfather the Divrei Chaim (see sources quoted below for the reasons behind this name). Renowned as holy from birth, he conducted himself with extreme holiness, would awaken every night at midnight to study Zohar until the morning prayers, and earned the reputation of a wonder-worker. He served as rabbi of Gorlitz, Koloshitz (Kołaczyce) and Zhmigrod (Nowy Żmigród). From 1904, he became the Rebbe of Zhmigrod. A foremost Rebbe of the Sanz dynasty, he was a diligent Torah scholar and preacher, a pious man reputed for the scope of his prayers. Near the end of his life, he relocated to Kraków.
His grandson R. Moshe Halberstam - later one of the rabbis of the Eidah HaChareidit Beit Din - travelled in his youth from Jerusalem to Kraków, to lay Tefillin in honor of his Bar-mitzva beside his grandfather, though unfortunately, WWII broke out just then. The grandson miraculously succeeded in returning to Eretz Israel, while the elderly grandfather escaped the Nazis to the Omsk forest, where he died of starvation. The family miraculously obtained a white cloth for his burial and even succeeded in laying a tombstone on his grave, but his writings were lost during the Holocaust (Rabbeinu HaKadosh MiTzanz, II, p. 369; Meorei Galicia, II, p. 528).
