Rabbi Moshe Natan Kahane Shapira (1852-1936), disciple of Rabbi Nachum Ze'ev author of Agudat Ezov and beloved disciple of his son the Rebbe, author of Avnei Nezer of Sochaczew who ordained him for the rabbinate and wrote about him: "His name is Shapira, he is Shafir (good) and his words are Shafir". He wed the daughter of the influential Rabbi Ya'akov Hendelsman of Radom and thereafter lived in Radom and studied with his brother-in-law, author of Chelkat Yoav who also was a disciple of the Avnei Nezer and son-in-law of Rabbi Y. Hendelsman. He became well-known as a leading Torah scholar and was famed for his diligence. Following the instructions of his teacher the Avnei Nezer, he also studied Kabbalah. In 1900, after many years of teaching Torah in Radom and in Miechów, he lost his fortune and was forced to serve in the rabbinate of the city of Kshoynge (Kielce region) and was noted for his Torah knowledge and proficiency in the laws of monetary issues, gittin and kiddushin. He was nominated for the Lodz rabbinate but preferred to remain in his position in Kshoynge. Only part of his large work Shemen LaMaor on Tehillim was printed among his manuscripts. The rest were lost during the Holocaust. His only son is Rabbi Mordechai Zvi Kahane Shapira Av Beit Din of Brzesko and Cracow [father of Rabbi David Kahane Shapira, a rabbi in Warsaw and of the Warsaw Ghetto]. His sons-in-law were the second Rebbe of Sochaczew, author of Shem M’Shmuel and Rabbi Eliezer Loewenthal Av Beit Din of Czeladź (adjacent to Będzin). 3 written pages, 21 cm. Good condition.
