Famous quotes containing the word roads:

    Then the master said to the slave, Go out into the roads and lanes, and compel people to come in, so that my house may be filled.
    Bible: New Testament, Luke 14:23.

    They’re busy making bigger roads,
    and better roads and more,
    so that people can discover
    even faster than before
    that everything is everywhere alike.
    Piet Hein (b. 1905)

    Lift your eyes
    Where the roads dip and where the roads rise
    Seek only there
    Where the grey light meets the green air
    The hermit’s chapel, the pilgrim’s prayer.
    —T.S. (Thomas Stearns)
