soon after the rebbe's announcement, eight yeshivas were opened – in będzin, podgórze, chrzanów, wolbrom, oświęcim, częstochowa, łódź and kraków. in the city of sosnowiec, the rebbe also founded kibbutz govoha, a high-level study group exclusively for advanced students and "avreichim" (married students). he appointed his new son-in-law, rabbi david moshe hakohen rabinowicz (1906–1942), a brilliant torah scholar, to head it. rabbi david moshe, a first cousin of the rebbe, married the rebbe's only daughter in 1929. he also served as rosh yeshiva of the entire keser torah network, monitoring students' progress, delivering "shiurim", and administering the end of the semester tests.
