 Ben-Gurion described himself as an irreligious person who developed atheism in his youth and who demonstrated no great sympathy for the elements of traditional Judaism, though he quoted the Bible extensively in his speeches and writings.Modern Orthodox philosopher Yeshayahu Leibowitz considered Ben-Gurion "to have hated Judaism more than any other man he had met".He was proud of the fact that he had only set foot in a synagogue once in Israel, worked on Yom Kippur and ate pork.
