Famous quotes containing the word day:

    “The Greeks used to say,” he said bitterly, using a phrase that had been a long time on his mind, “that when a man became a slave, on the first day he lost one-half of his virtue.”
    John Dos Passos (1896–1970)

    No prayers or incense rose up in those hours
    Which grew to be years, and every day came mute
    Ghosts from the ovens, sitting through crisp air,
    And settled upon his eyes in a black soot.
    Anthony Hecht (b. 1923)

    In the day of prosperity be joyful, and in the day of adversity consider; God has made the one as well as the other, so that mortals may not find out anything that will come after them.
    Bible: Hebrew, Ecclesiastes 7:14.
