"Oil is the most important product of the olive tree," said Miss Harson, "and it has well been called its richness and fatness. The great demand for it in Europe and Asia prevents the best quality from being sent abroad, and it is said that even the most wealthy foreigners seldom get it pure. It is a most important article of food, taking the place held by butter and lard with us. Innumerable lamps, too, are kept burning by means of this oil, and so varied are its uses in the East that it was a greater thing than we can understand for the prophet Habakkuk to say, 'Although the labor of the olive shall fail, ... yet will I rejoice in the Lord, I will joy in the God of my salvation.' Job says, 'The rock poured me out rivers of oil[9];' this means the oil of the olive, which will thrive on the sides and tops of rocky hills where there is scarcely any earth. It is a very long-lived tree, as well as an evergreen; the Psalmist says, 'I am like a green olive tree in the house of God.'"
