In 1903, he became rabbi of Moltsh, and in 1907 of Bransk.[3] Among his students in Moltsh was Yechezkel Sarna, who studied under Shkop for a year in 1906, before leaving to the Slabodka yeshiva when Shkop himself left.
In 1928, Shkop traveled to the United States in order to raise funds for the Yeshiva. After delivering a lecture at Yeshiva University, he became Rosh Yeshiva of Rabbi Isaac Elchanan Theological Seminary in New York. In 1929, Shkop returned to Europe. [4]
Death
As the Russian army was about to enter Grodno during World War II, Shkop ordered his students to flee to Vilna. He himself died two days later, on the 9th of Cheshvan 5700 (1939) in Grodno. Shkop is buried in the Jewish cemetery in the Zaniemanski Forshtat section of Grodno.
Works
His Sha'arei Yosher (1925), his most important work, is largely concerned with the intellectual principles by which the law is established, rather than with concrete laws, and is stylistically similar to the Shev Shema'tata of Aryeh Leib HaCohen Heller, on which it was partly based.
