Abraham ben Yechiel-Michel Catz Ha Cohen of Lask[a] 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.
He took his daily ablutions in the river before offering his prayers in the morning, often breaking through the ice in winter for this purpose.
At every stroke received Abraham uttered the rabbinic phrase, גם זו לטובה ("This, too, is for the best").
He published several kabalistic homilies, one under the title of Weshab ha-Kohen (The Priest Shall Return), Leghorn, 1788; another, Wechishab lo ha-Kohen (The Priest Shall Reckon), Fürth, 1784; a third, Bet Ya'akob (Jacob's House), Leghorn, 1792; and a fourth, Ayin Panim ba-Torah (Seventy Meanings of the Law), Warsaw, 1797.
