He differed from the Olympian gods of Greece, who were revelers, and from Buddha who tried to do nothing, or from Brahma who was only Thought. The Sabbath of rest implied other days of labor. In the book of Proverbs idleness is denounced as the cause of poverty and want.[366] Many passages are cited from the rabbinical literature in honor of productive labor and in disapproval of idleness.[367] In Book II, Chapter 62, of the Apostolic Constitutions, the basis of which is a Jewish work, it is taught that gainful occupations should be incidental and that the worship of God should be the main work of life.
