Rav Pinchas Ostrog

He was well known for his Chassidus and perishus – piety and sanctity. He would hide in the loft of the Great Synagogue, doing hisbodedus – attaching himself to Hashem in meditative seclusion. The townsfolk of Ostrog told many miraculous tales about him and said that even in his youth he was regularly visited by Eliyahu HaNovi.

His sons were Rav Yaakov Yosef II of Ostrog and Rav Moshe, founder of the Orzhitshev dynasty. His son-in-law was Rav Pinchas, grandfather of Rav Pinchas of Ostila.
