Abraham ben Yechiel-Michel Catz Ha Cohen of Lask was a Jewish ascetic who flourished at the end of the 18th century. He went to live at Jerusalem in 1785, but afterward traveled through Europe as an agent for the collection of donations for the Polish Jews in the Eretz Yisrael, making Amsterdam his center; he died as Hakam at Safed, during a riot against the Jews, who had protested against excessive taxation. Another version says he was punished by the Turks, in Jerusalem, (see below) and died in Safed, in 1799, there he was buried. He did not have children.
